How To Check A Compressor Windings. LG Linear Compressor Fridge Not Cooling How To Fix. Insulation resistance testing to check for degradation of motor winding insulation.
When a compressor shorts it often starts with a mechanical problem which can lead to an electrical problem later. If motor windings can be isolated its preferable to ground two sets of windings while testing the third set. A shorted motor will read 0 ohms across windings to ground or both.
If the compressor passes the above tests take a multimeter set to R x 10000 10K and check each winding to ground.
You should have an infinite OL resistance to ground. Insulation resistance testing to check for degradation of motor winding insulation. You need to figure out which posts correspond to the Start Main and Run windings cuz ifn you dont and you go and wire that relayoverload up wrong well you just went from a 30 easy-as-pie repair to a 300 rectal cramp. If the windings test OK but it still wont run then I connect a test cord and try to run it manually.
