I have a coleman heat pump.
Outside unit mod# 3330a901 SER# 10810578
Inside unit code & ser# 028261474 mod# 3300-815
DOE output capacity BTU 53,000
I have the original coleman thermostat with mercury bulbs attached to a lever.
I live in north central Texas where it gets over 100 degreesF.
I have a new fan motor on the condenser unit.
I had freon filled about a week ago.
While the a/c is running the compressor and cond fan will stop and cause the emergency heat to come on. The insider blower will continue to run until I turn it off. The emergency heat light will stay on and will not turn off for about 20 minutes then I have to turn the emergency heat switch on and off to get the light to go off. After that the a/c compressor will come on again and sometimes it will run for 20 minutes sometimes for an hour and this process will happen again. This morning after this process I turned the a/c on and it ran for about an hour and 10 minutes and the evaporator coil froze up.
Is there a relay or switch outside that might be failing or overheating and causing this to happen? Or what could be causing this to happen? Can I disconnect the emergency heat system so it will not heat my house in the summer?
Thanks,
Bill
