The condenser fan is a radiator-like device responsible for warming your refrigerator before the heat is transferred to cool areas. The metering device in most household refrigerators is a capillary tube, a tiny copper tube.
In a refrigerator, coolant is cooled in a condenser; from there it flow to the evaporator, where air is cooled by contact with the coil. Most common refrigerators have four major parts to its refrigeration system — a compressor, condenser, expansion valve, and evaporator. Free DIY advice on cleaning refrigerator condenser coils from leading home improvement expert Don Vandervort. A condenser fan is used on frost-free refrigerators that have a condenser coil in the bottom of the cabinet, inside the compressor compartment.
The first thing to understand is that all the cooling in a conventional frost free refrigerator usually originates in the freezer compartment, just a small portion of that air is circulated through the fridge compartment to cool there. The second thing you need to know is that the compressor (large black dome at the rear of the refrigerator) provides all the cooling ability for the whole appliance. Note: The compressor should usually be running whenever any of the fans (evaporator fan in the freezer and condenser fan by the compressor) are running. There is a difference between "frost" (a white, snow-like substance) and "ice" (usually clear and solid). Inspecting the (usually rear) wall of the freezer compartment for a frost build up is necessary. The refrigeration system's evaporator (cooling) coil is usually in the freezer compartment. The timer acts like a clock to automatically switch the refrigerator from cooling mode into the defrost cycle.
The defrost heater contacts of the timer or the defrost heater itself can burn out leaving the defrost circuit open. The defrost termination thermostat opens the circuit to the heater when it senses a set temperature. If the defrost termination thermostat contacts short out, it will allow the defrost heater to stay on as long as the timer is in the defrost mode. The defrost timer can also fail so that it powers both the cooling and the defrost circuit at the same time. The condenser itself can also become plugged with dust and dirt to the point where very little or no heat transfer can take place. On all frost free refrigerators there is a fan in the freezer section which circulates the air throughout the whole appliance.
If that evaporator motor should fail to function, proper temperatures will not be able to be maintained. On many older models, that evaporator fan may stop whenever the freezer door is opened, depending on the design of the refrigerator model and if a door activated fan switch is used.
Some newer model fridges (Amana, Frigidaire) and even some older models (GE in particular) run power for the evaporator fan motor through the defrost heater and defrost limit switch.
Still newer refrigerator models may use multi-speed DC motors which are electronically controlled.
Refrigerator models of late may utilize an automated air damper system to control the flow of air between the two compartments. The water that is recovered during the defrosting of the evaporator is funneled to the moistral pan under the refrigerator. Poorly sealing door gaskets can allow more warm and humid air into the appliance than can be remove effectively.
The light in either the fridge or freezer compartment may be staying on even when the door is shut.
Make sure that food packages inside the freezer and fridge sections are not packed so tight that it inhibits air movement throughout the compartments.
If only partially frosted (see illustration above) or if it just has just a single ball of ice in one small area, a qualified refrigeration technician will be required to isolate and correct the actual cause.

At left the thermostat wiring diagram illustrates use of a Flair APOV2 wall thermostat in a typical 2-wire application controlling a heating appliance. In this application the thermostat is acting as an spst (single pole single throw) switch to turn heat on or off, often by operating a zone valve. When used to operate a zone valve the thermostat wires are connected to the zone valve terminals, not to a primary control on the heating boiler. At left the thermostat wiring diagram illustrates typical use of a Flair APOV2 wall thermostat in a 3-wire application controlling a heating appliance. In this application the thermostat is acting as a single pole double throw (spdt) switch to control heating & cooling or in some zone valve applications.
At left the thermostat wiring diagram illustrates use of a Honeywell T87F thermostat in a 2-wire application controlling a gas fired heating appliance.

In the Honeywell T87F thermostat series the single pole double throw switch makes (closes) one set of contacts when the temperature falls - to turn on the heating appliance.
Above the thermostat wiring diagram illustrates use of a Honeywell T87F thermostat in a 2-wire application controlling an oil fired heating appliance.
At left the thermostat wiring diagram illustrates use of a Honeywell T87F thermostat in a typical 3-wire, open contact, high limit control such as on an oil fired heating boiler. At left the thermostat wiring diagram illustrates use of a Honeywell T87F thermostat in a 3-wire application as a spdt (single pole double throw) switch such as used to control low voltage motors, electric radiator valves, zone valves. At left the thermostat wiring diagram illustrates the typical wiring connections when installing a Honeywell RTH2300 (or similar) programmable room thermostat. Watch out: existing thermostat wires that will not be used in the new thermostat installation, such as wires attached to C or C1 terminals on the old thermostat should have their ends taped so as not to accidentally touch and short other thermostat wires or connectors. Honeywell Series 10 controllers such as the Honeywell R19A use a simple relay and built-in transformer and one or more line voltage contactors. In this sketch from a 1949 Honey Heating Control Handbook the thermostat has been satisfied (both contacts are open) and the system is not calling for heat.
Understanding the wiring details of series 10 controls and circuits can help us diagnose heating and cooling system operating snafus.
The White Rodgers 1F90 and similar models will replace most 2-wire heating thermostats and many 3-wire & 4-wire thermostats used for both heating and cooling. Continue reading at THERMOSTAT INSTALLATION STEPS or select a topic from the More Reading links or topic ARTICLE INDEX shown below.

Note: NeverClean If the refrigerator uses a fan to keep the condenser cool, then this must be cleaned, at the very least, yearly. One of the most common causes of poor cooling in a frost free refrigerator is a defrost system failure. When referring to what is seen during an inspection, please keep this distinction in mind as the possible causes for each are often very different.
This evaporator will periodically frost over and have to be defrosted by means of a heating system. After a period of time it then switches the refrigerator out of the defrost cycle back into the cooling mode again. If this happens during the cooling mode, it will allow excessive frost to accumulate on the cooling coil reducing air flow, eventually stopping it altogether as it never switches into defrost mode to melt it. In this case even if the timer advanced into the defrost cycle, the heater would not produce any heat to defrost the evaporator coil.
This set temperature is usually high enough that the cooling coil should be totally defrosted by then.
A symptom of that is usually greatly fluctuating temperatures in the freezer compartment possibly causing thawing and re-freezing of food stuffs. This can cause both the fridge and freezer section to not cool properly and will likely be noticed most in the refrigerator section. It should be checked to ensure it is operating and at full speed whenever the compressor is running. It should be thoroughly cleaned several times a year to avoid cooling problems and keep the appliance running as energy efficiently as possible. Those areas are often heated by tubing incorporated into the refrigerator's cabinet which is part of the refrigeration system's condenser loop. That fan is called the "evaporator fan" and should usually be running whenever the compressor is running. Failures could include the motor winding becoming open, the motor bearing seizing, the fan blade's movement hampered by an excessive frost accumulation on the evaporator coil or the motor running slower than normal because of worn motor bearings which can also result in a squealing or squeaking sound being emitted. Such a fan switch was eliminated from many never fridge designs as it was a common failure location which would stop cooling of the whole appliance should it fail. If either of those components should fail, the fan may stop circulating cold air through the entire refrigerator cabinet. Such designs can experience problems with a motorized damper and if employed, may be suspect for either limited cooling in the fridge compartment or freezing temperatures there. The drain trough in the freezer compartment below the evaporator which catches that water can get plugged with food residue, etc. If you experience this on a newer top-freezer fridge design, you should consider having a *factory authorized* technician see if any design modifications are necessary on your model to correct this occurrence.
This will often lead to excessive frosting of the evaporator coil that even a properly operating defrost system can not handle. The door activated light switch can usually be pressed manually to ensure it is still operating and not shorted.
This will involve inspecting the evaporator (cooling) coil itself and looking at the frost pattern on it.
The refrigerant used in refrigerators is usually either R12 or on most newer fridge models, R134a.
Also at least some manufacturers' instructions call for installation of the thermostat by a qualified technician. Unlike the remaining wiring diagrams in this article, the AR61 is a controller, not a thermostat.

More wiring diagrams are given in the Chromalox HeatFlow installation manuals linked-to below.
This second set of contacts is typically used to operate a cooling or air conditioning system but may also be used to operate other controls or valves in some heating systems.
Be sure to identify and label the existing thermostat wires before disconnecting them from the terminals on the old thermostat you are replacing. On a drop in temperature the flexible blade makes the white contact, and subsequently connects the stiff blade.
It is not used on systems without a transformer or relay, hot water heat systems that use 3-wire zone valves, two-stage heating or cooling systems, and certain other applications. The book provides comprehensive coverage of wiring and technical specifications, and now includes increased coverage of combination boilers, recently developed control features and SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK) boilers ratings, where known.

The text is intended as a reference guide to help building owners operate and maintain their home effectively. There are two sets of coils for cooling appliances like refrigerators, they are called the evaporator 3 and condenser 1 coils.
Warm air is circulated into the freezer compartment where its heat is removed by the refrigeration process leaving behind cooled air.) In any case, if that air flow is hampered in any way, cooling problems will result. As long as the compressor is running, the possibilities listed below will need to be checked one at a time. In such a case one or the other compartment may appear to be keeping proper temperature but that too may change in a short period of time. When the defrost heating system fails, the frost can accumulate to such a degree that airflow throughout the appliance is hampered. When the defrost heater is switched on during the defrost cycle, it melts any frost build up which has accumulated. The timer can also stick in the defrost mode and never advance into the cooling cycle again. The timer then goes merrily on its way back into the cooling cycle, effectively accomplishing nothing. If this device fails and remains permanently open, the heater would never get power to defrost the evaporator. If the main condenser can't off-load the refrigerant heat normally, that heat will migrate to those areas of the cabinet causing unusually warm temperatures there.
Besides hampering air circulation, failure of this motor can also result in an excessively frosted evaporator coil. On most older models the air damper system is manual, adjusting an air duct 'flapper' by turning one of the control dials.
This may also cause condensation to appear on various areas on the interior like the refrigerator section ceiling or inner door panel. When operating normally there should be a complete and even frost pattern across the whole evaporator.
And in the tables given in the article above you will find explicit wiring instructions for most common room thermostats.
If the batteries fail the thermostat may fail to provide heating or cooling and the building may suffer accordingly.

Counter-Depth French-Door Bottom Freezer Refrigerator, Whirlpool The refrigerator condenser coils are the black coils found usually at the back of the refrigerator.
If the compressor is not running or continually trying to start but failing within seconds, clicking and then shutting down, someone will need to look into why.
The fridge compartment's temperature rise is usually (but not always) the first to be noticed. There may be just enough air circulation to cool the freezer section but that will eventually stop too. The defrost limit switch shuts the heater off when it senses a set temperature which should indicate a totally defrosted evaporator. These older systems were rarely the cause of problems without having been physically tampered with in some way. This ice blockage can hamper the air flow from the freezer section into the refrigerator compartment, causing warmer temperatures in that compartment. Other refrigerant manufactures have their own brand names that they market their refrigerants under.
