Tempstar heat pump: want to bypass defrost thermostat

Our heat pump is wanting to go into defrost mode constantly when we have it turned to heat. It attempts to go into defrost, but it sounds as if it keeps tripping a switch on and off and it repeatedly gets louder. So we end up using the emergency setting when this occurs.

We live in Clearwater, FL and I don't think we really need the defrost cycle. Can I bypass it? It's a Tempstar heat pump that was installed when the house was built in ''91''. It has served us well with no problems.

Thank you for your kind response,

Mr. K. Greene

Don't attempt to bypass defrost mode. If it's cold enough to use as a heat pump, it's cold enough to need the defrost cycle.

It sounds like a sensor issue, although it may be the controller board.

Unless you know how to work on equipment like this, I urge you to get a professional to service the unit for you.

Sound to me that you might have more of a defrost sensor problem or micro board in the condenser (outside unit).. and no you should not bypass what its design for, it can hurt your unit... and at 18yrs old unit.. thats a good one...good luck..mike

I have a Rheem Classic Super Quiet 80 gas furnace (for heat). The fan stops when the "heat" turns on.


Any time I ever had trouble,first thing to suspect is the thermostat.
They lose contact sometimes and sometimes you tap the face and they work til next glitch.
If the thermostat has some years on it,go ahead and replace it.
Can't you just leave the heat and fan in auto? That would be best,I think. don-ohio

I have a older Carrier heat pump, model 38YKC060. Does anyone know how cold it will continue to work at?


Heat pumps are of little or no value at temps around 40 degrees or below. And if you use the strips it will cost a small fortune if you have relatively high electric rates as most folks do.

I have a 9610 thermostat turns on and off to frequently


I am guessing but the thermostat is either faulty or is in conflict with another thermostatic device in the system. The room thermostat measures the air temperature in the room but with a modern intelligent boiler there will be other sensors measuring all sorts of things including the water temperature.

Personally I prefer to have thermostatic radiator valves rather than a room or zone thermostat.

My thermostat is set on 68 degrees and it shows room temperature is 68, but the furnace still kickson, Honeywell said it has a 1 degree difference. so what's the problem then?


Yes there is a one degree tolerance, in fact my heater just kicked on and it is set to 67 and the inside temperature reads 67. It is also a Honeywell.

My termost set to a/c, the fan auto, blow very well, but when I switch to heat and the fan auto, doesn't work, but if I put fan on work why?


the thermostat says to call for heat buildup in the work if its not cold enough the thermostat won't call for heat and I won't go on but when it gets cold and the thermostat set to the temperature you want or hire someone that doesn't cycle

I have a Coleman Evcon electric furnace, the blower fan runs constantly and I have to shut the breaker off inside the front cover to turn it off. The switch is on auto and it runs even when the thermostat...


It could be a thermostat problem. Also it will seem to run constantly as it tries to heat and one of the elements are working which could be a sequencer problem.

Flashing re co


Re Co stands for Recovery Mode. That means if you have programed your thermostat to be at say 72° at 5:00 then it should kick on in Recovery Mode several minutes before 5 in order to reach that temperature. This is normal and doesn't indicate that something is wrong, just that your thermostat is trying to reach or recover the programed temperature.
