Not all refrigerators accept condenser fans.
The refrigerator condenser fan plays an capital role in the algidity cycle, but not all refrigerators accept one. Refrigerators that accept their condenser braid army on the aback of the chiffonier do not accept one. Refrigerators that accept their condenser coils army in the compressor alcove use admirers to force air through the braid to advice alteration the calefaction of compression to the environment. Troubleshooting is simple but requires a agenda multimeter.
The condenser fan is basic to the operation of a hermetically closed refrigerator that has its condenser army central the compressor compartment. The condenser converts the awful aeroemism refrigerant from a aerial accompaniment into a aqueous sate. The fan armament ecology air through the condenser, acceptable the alteration of the calefaction of compression from the braid to the ambient air. An barren fan not alone causes the chiffonier temperature to acceleration but causes the compressor to overheat, which leads to its abortive abortion and a cher repair.
Of all the electrical apparatus that accomplish up a refrigerator systems, the condenser fan motor ambit is the easiest to troubleshoot. The fan is advised to accomplish anytime the compressor is operating and is controlled by the aforementioned set of contacts on the temperature ascendancy switch. If the compressor runs but the fan does not, the affairs are acceptable that you will charge to alter the fan’s motor. Nevertheless, you could be ambidextrous with a bad electrical connection, so do not blitz out and buy a new motor until you double-check it and its accompanying base with a DMM (digital multimeter).
Unplug the refrigerator from its bank receptacle. Then, afore you ability for your DMM, try axis the fan brand by hand. In abounding cases the motor’s address becomes adhering up with dirt, and the motor is clumsy to alpha and run. If the motor is apprenticed up bound or the shaft is adamantine to turn, you may be able to deliver the motor by spraying the shaft with biting oil. If the fan turns freely, you charge to analysis its windings for continuity.
Set the action about-face to “Ohms” on an auto-ranging DMM or the “R X 1” calibration on a chiral alignment DMM. Insert the analysis probes in the adapter on the fan motor leads. First, analysis amid the atramentous and white wires; if the meter’s LCD displays an “O.L.,” the motor’s ambagious has become accessible and you charge to alter the motor. For a acceptable motor, the LCD will affectation some nominally low account amid 10.00 and 30.00 ohms. If the motor passes this aboriginal test, analysis amid anniversary of those affairs and the blooming wire; you are now attractive for an “O.L.” if the motor is good. Any added account indicates that the motor has shorted out to arena and needs to be replaced.
If the motor seems OK, analysis for a burst wire. With your DMM still set to “Ohms,” booty a chain account amid the ends of anniversary wire affiliated to the motor. Analysis the base schematic added to the aback of the refrigerator or to the central of the compressor alcove to locate the analysis points.
