My Lennox HS25-651-1P compressor has stopped working. Here is the stroy:
- Thermostat turns on attic furnace/blower unit.
- Outside comprssor does not go on.
- Tested and replaced 60A fuses at comprssor.
- Tested and confirmed power to input side of relay in compressor (240V, 1P)
- It appears that there is power at thermostat leads in compressor (only setting on multimeter that displayed reading was DC milli volts as my meter does not have AC milli volt setting).
- With everything connected and thermostat on the relay is not connecting and compressor does not go on.
- There is visible rodent damage on wire casing to capicitor but wire is not chewed through, only casing is gone and wire is not touching any metal.
My thoughts are as follows:
- power is not getting to relay to activate it (switching problem)
- defective relay.
- capacitor problem?
Please reply iwth any suggestions for diagnosis/repari.
Thank you...
