My simple comfort 2200 thermostat has a brown wire hooked to the e terminal. what is the e terminal for?


Likely for emergency heat. When the heat pump is in defrost mode, due to extremely low ambient temps, e is your indoor heat strips.

My Jandy Heat Pump goes into defrost mode all the time


The heat pump works almost like an air conditioner or A/C but not entirely, as a matter of fact it works a lot more like a refrigerator. Not only does it help lower down the temperature at home during the hot months, it can also operate in reverse and it can actually act as an indoor heater and provide warmer air inside the house during the chilly winter months.

I have a goodman self contained heat pump that is 3 and 1/2 years old. I wake in the night to hear what sounds like the fan runnning and running and running and air moving thru the vents. Then I will hear...


Heat pumps are a very efficient design when working properly. But lose efficiency the colder it gets outdoors. I usually tell people when it drops below freezing to turn the thermostat to aux or em. heat. A heat pump can remove heat from 20°f air. But not very well. More heat at 30°f air, obviously, and so on. So the colder it is outdoors, the longer it will operate to remove heat from outdoors. And then, if it can't keep up, it brings on the electric heat elements to compensate. Now you are running both outdoor and indoor heat. This is where it's inefficient and costly. Also, the outdoor will start to freeze up. This is normal unless you can see a substantial amount of ice. The heat pump will engage defrost mode, cycling on the electric heat indoors. And defrost mode is actually cooling mode! The reversing valve in the heat pump switches to cooling mode, cycles off the outdoor fan, and defrosts for a set time or temp. So now your electric heat is engaged, and your indoor coil is a COLD coil! Not hot! Very inefficient. These 2 things are why your elec bill is higher in the winter. So it makes sense to me, if the elec heat is going to be on anyway, to move the tstat to aux or em. heat, when it's going to be below freezing outdoors. This will turn off the heat pump and use elected heat only. The only down side to this is, if you don't have enough elec heat to keep you warm, you may need both heat pump and elec heat. So trial end error until you find what works. Also, have a qualified tech check the system for operation and efficiency. Hope this helps!

Indoor fan blowing cold air when on heating


The indoor fan will continue to run. When heat pump goes into defrost the outdoor fan stops, the reversing valve switches and the unit is basically working in the cooling mode. In order for you not to feel a blast of cold air in the winter the electric strip heat also comes on so the indoor fan must run while the strip heaters are on.

Sometimes the auxilary heat light comes on, and this morning the auxilary and emergency lights were on. Our electric bill has been really high the past two months.


Assuming we are talking about a Heat Pump system with an outdoor condensing unit and an indoor air handler, it is not uncommon for electric bills to escalate during the harder winter months.
Typically, the auxilary heat light energizes whenever the electric strip heaters are in use. These heaters are used to supplement the heat from your heat pump system which will be unable to maintain desired occupied setpoint with outdoor temperatures below 35degF. At outdoor temperatures below 35degF is not uncommon for the heat pump to run non-stop and the electric heaters will cycle on and off as the temp in the house drops between 1/2 to 1 1/2degF below setpoint. The electric heaters will also come on when the system goes into a defrost mode...defrost modes typically last anywhere between 2 - 8 minutes. The emergency lights, depending on your thermostat, will come on whenever the thermostat is placed in EMER HT. Some systems energize the emergency heat lights to indicate there is a problem with your condensor unit.
I suggest you ensure the thermostat is in HEAT mode and not EMER HT mode. Also, while the system is running, step outside and visually inspect your condensing unit. Is it running? Does it appear and sound like it is running normally?
Don't forget your air filter. This is the single most important and most-neglected maintenance item on your system.

If after these steps, you still feel as though you are having problems and would like to try and correct them yourself, please let us know.

I hope you find this information helpful. Good Luck to you! :-)

Heat strips do not energize during defrost cycles air below 50 degrees up to 14 minutes


if your heat strips are not coming on, then there are a few things to check.

The first one would be that the heat strips are actually working. The easiest way to complete this task is to turn the system on into emergency heat and turn the thermostat up. If you get heat accompanied by the traditional strip heat burnt smell, then you know the electric heat strips are working.

The second thing would be that the air handler is receiving a command for heat during defrost cycle. If the command is present with no heat, then you most likely have either a wiring issue or a failed electrical relay or contactor.

The third thing would be the defrost board itself, for it is the component that calls for electric heat strips to come on during a defrost cycle. You may or may not be able to force the defrost board into a defrost cycle and then check that the heat strips are on or not.



It sounds as though your defrost board is bad with the symptoms you are describing.

Good luck.

MY HEATER BLOWS HOT AIR THEN BLOWS COLD THEN HOT THEN COLD,ICHANGED THE MOTHER BOARD, RELAY SWITCH, AND THERMOSTAT, IT IS RUN FROM A HEAT PUMP WITCH I HAD CHECKED AND IT WORKS FINE


I have a lux electric thermostat my furnace will blow out heat for about one hour to maybe three then it will start blowing cooler air,I then cut it off for thirty seconds or longer once I do that it will start blowing out heat again then it will repeat it self again what could be the problem.

I have a westinghouse window unit and I think it has heat strips for the heat. How do I tell if it is a true heat pump or if it has heat strips and how do I get to the Heat strips in the unit to check.


If it is a heat pump, the compressor will be running both in cool mode and in normal heat mode.

Confirm the current indoor temperature. Turn the thermostat up one degree at a time until it comes on. This will typically be 1 to 4 degrees increase. As soon as it comes on stop increasing the temp.

If the compressor is running, it is a heat pump.

Check the temperature coming our of the vents at that time. You should have 30 to 60 degrees increase from the air temp going into the unit and the conditioned air temp coming out.

Then turn the T-stat up another 10 degrees. If the temp coming out of the vents increases by 20 degrees or more. the strips are on.

The strips operate in three situations.
1) the system is set to emergency heat
2) The heat pump cannot keep up with the demand for heat. (because its too cold outside, the desired temp setting is greater than 4 to 8 degrees above the room temp, or the HP is malfunctioning.)
3) The HP is in defrost mode

You could also take the panels off the unit and look for a reversing valve, but unless you know what you are looking for you will not recognise it.

Goodman heats but defrosts turns on before desired temp.


Yes. The defrost cycle of a heat pump is actually turning on your airconditioning to heat up the condenser to thaw it out. During this cycle your electric strip heaters "should" be adequate enough to compensate for the a/c being on. At about 30 - 34 degrees outdoor temp there is not enough heat in the air to to adequately heat your home with the heat pump only. Some technitions will use an outdoor thermostat to turn off the heat pump when it is under 34 degrees outside. If you are to cold when its under 34 degrees intall more electric strip heaters.. But if you do this your electric bill may go up significantly.
Welcome to the wonderful world of electric heat pumps (lol).
Good luck.
