The A/C compressor turns on and off repeatedly. It doesnt happen everyday though. Sometimes its working fine no matter what the outside temp is. I found the condenser fan not running when it should be running together with the compressor. Used light tester to check wires going to the fan, no power. On another instance, there was power. I wired fan direct to battery, continuous running.
When there is no power going to fan, I tried interchanging the relays for compressor and fan, still no power. I checked with light tester the sockets for the relay, two points were giving power.
One time while observing the a/c in running condition, thermostat switched off fan and compressor(already cold). When it kicked back in, compressor and fan started, but the fan immediately lost power and stopped.
One time A/C was switched on, high pressure switch on receiver was disconnected to prevent compressor from running, inside blower was set to #3, condenser fan was not running. When I changed the blower switch from #3 to #1, condenser fan started running.
Suction pres. Is 30psi, disc pres. Is 200psi. Ambient temp. Is 28 deg Celsius( 82 deg F)
What should I do next?
have the same problem?
