This time the compressor ohms out correctly. Now the tech needs to determine why the compressor overheated. An overload might open due to: A lack of maintenance. If the outdoor coil gets dirty it can raise the head pressure and make the unit run hot. A defective run or start capacitor. These two items need to be checked. Touch test probe to shunted compressor terminals. Depress test button on test probe (or on meter) for test duration period (60 seconds). Record resistance value and terminal temperature. Remove shunt across compressor terminals and restore to proper electrical connections. Place compressor in operation for 5 or 10 minutes.If the condenser fan doesn’t when the compressor is on, then is due to one of the following reasons: Condenser fan capacitor is bad. Fan contactor isn’t working. Fan motor is bad. Shut off your AC and check the fan capacitor, contactor, and motor if the condenser fan isn’t running when the compressor is on.ISOLATE THE COMPRESSOR: “Unless you pull the compressor from its terminals, you cannot know it’s shorted,” said Orr. “If you’re reading at the contactor or anywhere else, there could be a …How To Ohm Out A Compressor Likewise, people ask,how many ohms should a compressor have? The lowest reading should be below 10 ohms (this is the run winding). The second highest reading should be about 2-4 times higher than the lowest reading (this is the start winding).CoreSense Diagnostics for Copeland Discus Compressors.
