If the motor seems OK, check for a broken wire. If you placed an order on ApplianceHelp.com the order is still valid and you can check on its status and make changes here on PartSelect.com. Of all the electrical components that make up a refrigerator systems, the condenser fan motor circuit is the easiest to troubleshoot. A defect in any of these components can cause a symptom of running too long or not cooling enough, and would have to be tested and/or serviced by a qualified refrigeration technician as it involves live voltage tests. A slow-turning air conditioner fan is not good news during the dead heat of summer. If the fan blade does not turn freely, check to see if the blade is rubbing against something or if something is caught in the blade. Locate the evaporator fan motor, it will be behind the evaporator fan cover, inside the freezer compartment. This can leave the fan motor running. Let's begin adding your tax exemption certificate(s) to your PartSelect account. A failed PTC starter relay on the compressor could also be causing this problem with the compressor starting.

I just replaced the evaporator fan motor in a relative's refrigerator. Nevertheless, you could be dealing with a bad electrical connection, so do not rush out and buy a new motor until you double-check it and its related wiring with a DMM (digital multimeter). I recommend that you unplug the refrigerator since the compressor is not running. How to test a refrigerator defrost timer with a multi-meter: The defrost heater is controlled by the defrost timer or adaptive defrost control and the defrost termination thermostat. Adaptive defrost controls will monitor ambient conditions and previous defrost cycles and adapt the defrost cycle frequency and length to be more efficient. Set the function switch to "Ohms" on an auto-ranging DMM or the "R X 1" scale on a manual ranging DMM.

You will need to remove the rear access panel to find it, it should be near the compressor. If it is warm (anywhere from forty to ninety degrees Fahrenheit), then this test should produce a reading of infinity. A defective thermistor may cause the evaporator fan and compressor to run too slow or too fast, which will make the refrigerator warm. Newer style thermostats may have an internal bias resistor to aid in testing both the thermostat and the heater. If debris accumulates on the coils, the refrigerator will have to work harder to remove the heat. The second pair may also result in a reading of zero or near zero. You should also inspect the fan and motor for any signs of wear or damage, removing any foreign objects in the area. The fan forces environmental air through the condenser, aiding the transfer of the heat of compression from the coil to the ambient air. Testing the third pair of terminals should produce a reading of infinity. Insert the test probes in the connector on the fan motor leads. Unplug the refrigerator and remove the screw that holds the control box. If the refrigerator has had a slow refrigerant leak, you’d notice it pinging and banging as it tries to move refrigerant through the pipes even as some escapes.

Unfortunately this condition could indicate a burned-out A/C or heat pump compressor motor. If you notice a large amount of ice has built up on or around the motor, allow your freezer to defrost and see if that resolves the issue. If the condenser cannot expel heat efficiently, then the compressor and sealed system work harder to keep the refrigerator cold. Still not sure which part is broken? When your thermostat is cold, it should produce a reading of zero on your multi-meter. Measured between pin 3 (FAN COM) and all the other wires. Let's check the wiring first. Usually it is accessed by removing the bottom back panel. The torque to drive the motor of your electric fan comes from the magnetic field induced in the motor coils when electricity passes through the coils.

The fan is designed to operate anytime the compressor is operating and is controlled by the same set of contacts on the temperature control switch. The condensor fan is running slowly (5 to 10 revs per second). Remember, you get only the motor, you have to use the old fan blade. If the motor passes this first test, check between each of those wires and the green wire; you are now looking for an “O.L.” if the motor is good.

The condenser converts the highly compressed refrigerant from a gaseous state into a liquid sate. If the evaporator fan does not work then the control thermostat or sensor may not correctly sense the temperature and the compressor will continue to run longer than normal. Then, before you reach for your DMM, try turning the fan blade by hand. 3. This fan keeps air moving to expel heat, so if it is not working right, the compressor has to run longer to cool the fridge. I might have noticed a leak by the bubbling on the coils, if I ever actually looked at them. The tubes attached to the condenser also run in the space between the fridge and the freezer doors, so it that area feels warm, your problem could very well be the condenser fan. For this reason it is sometimes difficult to check the continuity of the thermostat unless you are sure that the temperature is low enough to close the circuit. How to inspect a refrigerator condenser fan motor: The evaporator fan is used to draw air over the evaporator coil and circulate the cold air throughout the fresh food and freezer compartments. The frige works fine ( 0°F freezer temp) with an external fan blowing on the condensor fan through the slots of with the back cover. We will notify you via email once verification is done. Troubleshoot wiring problems. The refrigerator condenser fan plays an essential role in the refrigeration cycle, but not all refrigerators have one. You’re right – without a refrigerant, a refrigerator is an over-aerated pantry. If the coils are significantly dirty, the refrigerator will run constantly in an effort to cool down. You could have a locked up compressor or a bad compressor motor. Testing the first pair should produce a reading of zero, or near zero, denoting continuity. The condenser fan may be mounted in a number of different ways. How to test a refrigerator defrost heater with a multi-meter: The defrost termination thermostat is used as a safety device to turn off the defrost heater when the temperature reaches a specific limit. Removed two screws to remove the fan motor from mounting bracket. Check to see if the condenser fan works when you see the freezer not getting cold enough. Faulty temperature sensors or controls can also prevent the freezer from cooling well. Yes a slow moving fan will cause the refrigerator section to get warm. Troubleshooting is simple but requires a digital multimeter. Mechanical timers are more common and usually activate a defrost cycle every 8-10 hours of compressor run time. If it is noticeably worn, or if it is seized, you need a. Should you need to upload, just click the "Import your copy of this document" link in the form.

If the compressor won't start and if the unit trips a breaker or blows a fuse as soon as it tries to turn on, the motor is burned out and shorted. The condenser fan is vital to the operation of a hermetically sealed refrigerator that has its condenser mounted inside the compressor compartment. We can offer you custom troubleshooting help if you search with your model number. Adding a certificate takes only a few moments. At various points around the fridge, place a piece of paper on the seal and close the door normally.

Refrigerators that have their condenser coil mounted on the back of the cabinet do not have one. The motor and fan is from a desk fan I put in there. The heater is normally a glass encased heater wire with well insulated wire leads. With your multi-meter on the Rx1 setting, touch the probes to a thermostat wire. DIAGNOSIS AND REPAIR. If you receive a reading of zero or infinity, you will need a. The refrigerator condenser fan plays an essential role in the refrigeration cycle, but not all refrigerators have one. Moisture along the edge of the door is also a good indication that the gaskets are not sealing properly and should be replaced. If the fan turns freely, you need to check its windings for continuity. With fan motor loose, I removed the fan propeller from motor by pulling it off the shaft.
