Check the blower motor capicator. It should be mounted close to the motor with 2 wires to it (brown,brown/white).
Turn the blower on the thermostat and spin the squirrel cage by hand and see if it runs after by itself. If it does then definitely the capicator is bad .If it still doesn't run then check to see if there is voltage going to motor.
If thermostat is calling for fan and there is voltage present at the motor terminal then the motor is bad

We have a new a/c and the system has heat strips. For a/c. we have had the thermostat set on AC at 72degrees. Now that it is getting colder and may need some heat in the house, do we switch the...


If your thermostat has an emergency heat setting this means you have a heat pump system.
Yes you need to set the thermostat to heat for heating the house.
The emergency heat setting should never be used unless your outside unit is not functioning.
The emergency heat setting overides the heat pump (the outside unit will not be energized).
The emergency heat setting will run the auxillary heat (heat strips) only.
When the thermostat is set in the heat position the heat pump will run to heat your house.
If the heat pump can't keep up (extreme cold) then then the auxillary heat will kick in to augment the heat pump until it satisfies the thermostat settings. If your room temperature gets 2 degrees below your thermostat setpoint, your auxillary heat will kick on. Example, say you are going to be gone a couple of days and you turn your heat down to 60 degrees. When you return and it is 60 degrees in your house, you turn the thermostat up to 70 degrees. Since you are turning the temperature up 2 degrees or more (10 degrees in this case) from the 60 degree room temperature then the heat pump will come on and the auxillary heat strips. The unit will continue heating like this until the temperature in the house gets to 69 degrees and the heat strips will turn off and the heat pump will continue to run until the 70 degree setpoint is reached.
Hope this helps.

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! :-)

It sounds as if you you have a low charge of refrigerant, r22. When the unit comes on outside, the outdoor coils become the lowside, there is a low pressure switch that is tripping out contactor protecting the compressor.

Armstrong 4PHP13E36P runs after heating element cools


There may be pins on the circuit board inside the air handler that you can adjust. First turn off the breaker then look inside at the board. They may say 30-45-60-90 etc. Put the pin on a lower number. Do you have a digital or programmable T-stat? There may be a setting in the T-stat setup program that allows for blower delay also. consult you installation instructions. Last if the blower isn't turning off at all then the relay on the circuit board is stuck closed and should be replaced.

Rheem heat pump. blower will not turn off


The fans are set to delay for 60-90 seconds to remove all heat from the heat exchanger/heater elements.

If the fan runs any longer than 3-4 minutes after the Emergency Heat shuts off, you may have a bad sequencing relay in the air handler.

If you have a volt meter, check to see if you have 24 volts coming from the thermostat on the yellow wire.

If you do, and it is set on emer heat, you have a bad T-stat.


It looks like it is wired properly.

If you have no meter, you could try changing the stat, I reccomend Honeywell or white rodgers.

Let me know if you eliminate the Tstat as the problem and we can go from there.
Chances are its the stat.
