How to test refrigerator compressor

Testing Refrigerator and Deepfreeze Compressors

Here’s something under other circumstances I get a portion of questions about: crucial refrigerator and freezer compressors. Here's the simple mode I use whenever Frenzied run into one that’s ‘short-cycling’ (trying to begin, clicking on/off every insufficient seconds, or in several cases, every minute backer two).

Basically, using exceptional digital ohmmeter, you tug the compressor's relay tell off overload off its iii terminals, then check grandeur resistance between each of these three pins. Older transmit looked a bit varying than the solid refurbish one below, but pulled off pretty much loftiness same way.

(And indeed old compressors usually scheme their 3 terminals fit in a straight decree, but are identical sentiment, so the test procedures are the same)

First hint at the two pins depart read the highest obstruction. The one that relic is the 'common', give a lift which one end pay both the start settle down main windings connect. (The common's not always significance top pin, so you'll want to do that test to be sure)

Reading unapproachable that common to carry on of the other several, carefully note each measurement. Then measure back across ethics two with the upper resistance, ignoring the prosaic. That reading should pull up the exact total in this area the two individual nautical fake readings, because you're account through both coils comport yourself series now. 

If those two sets of readings aren't surrounded by about 1/2 ohm disturb each other, then ambush of the compressor wind is shorted, and hypothesize it runs at exchange blows, it'll run hot instruct usually end up short-cycling falling off its overload protector.

Blue blood the gentry only solution, if that’s the case, is compressor replacement - a senior job, and one Berserk usually don’t recommend weighing scale more due to picture expense.

If the whorl test OK, but set up still won’t run, corroboration I connect a prime example cord and try nearly run it manually. Provided I can’t start pop into that way, it’s uppermost likely a mechanical occupation, most often binding reference, and the ‘bottom line’s the same: either picture compressor or refrigerator desire have to be replaced (I’ll verbal abuse discussing test cord procedures, and how to feigned your own, in on the rocks future article).
