Questions & Answers

For Whirlpool Freezer Compressor Overload Protector (Part Number: OEM18019926)

1 Answer

John,

You will want to check the evaporator coils for being impacted with ice or only a partial frost pattern. The partial frost pattern may be a sealed system issue and if the coils are impacted with ice the a defrost issue. You would need to do a continuity test on the defrost heater and thermostat. If they have continuity then the defrost control would be the issue. The overload and relay would not be the problem with the compressor running all the time.

John,

Based on the compressor continuously running and the compressor checking ok then it sounds like the unit may have a leak of the refrigerant. You can do a amp draw and see what the amp draw on the compressor is. If the amp draw is higher than 1.0 amps then it may have a restriction and if lower than .5 amps then it would be a leak.

Art, If you have the proper power supply (120 VAC) at the outlet, then you may have a weak overload WP2214067 or start relay WP2262181 . There is the possibility that there is a sealed system failure(inefficient compressor or restricted system). and this would require a licensed, certified technician to repair.

Scott, You should have no 0 (infinite resistance) "open" circuit readings. The overload WP2214067 should have a "closed" circuit (000) across the terminals at all times. The capacitor WPW10662129 when tested, your meter will deflect towards a "closed" circuit, then drop back down to 0 (infinite resistance). You'll need to remove the the start relay W10920279 from the compressor and test from the top pin (c) to the pin on the bottom left(start) and you should read 3 to 11 ohms. and from the top pin to the the bottom right pin (run) should read 1 to 6 ohms resistance. Make sure you label or mark the wires when you remove them from the terminals on the components.
