Have the original Coleman R-22 AC's,they have 2 knobs,1 for on, off and speeds and 1 for the temp from hot to cold.The last week or so when you shut the unit off the compressor still wants to kick in even with the switch off,if you turn the thermostat knob from
cool to the hot setting it finally stops, think maybe Iv'e got a relay or something sticking on,any ideas?
Ordered a new solenoid and thermostat,will see if that works.
See, Dave. That's what you get for coming up here and loving our Mills Fleet Farm and saying bad things about your Tractor Supply!
Go pull that isolator out.
Isolator checks good. Alternator checked bad.
