Inside blower will not turn off after outside unit turns off. Thermostat fan control set to auto. When I set it to emergency heat fan turns off after house is warm. Thermostat has not been changed. The only way to turn fan off is to turn the thermostat off.

if this is indeed a heat pump you rthermostat should also have a emergency heat setting does it work on that setting... a heat pump on heat wuns the outside unit and has a recersing valve that changes the refigerant flow ..is the outside runnignduring heat mode... if you turn the thermostat in emergency heat the outside should shut down and indoor heat should come on...of this is not happening you have a wiring issue if both are not working... braeburn thermostats usually have behind the cover dip switches... i am not exactly sure what model this is but if indeed a heat pump the thermostat should have a r,w2,y,e,g,c,o,and b terminal... rheem wiring should be as follows
red to r white to w2 , g=green , yellow to y terminal there should be a wire hooked to the b terminal usually brown sometimes orange on the b terminal that is your reversing valve terminal.
you are going to have to make sure the thermostat is configured to energize the b termianl and will have to go into the installer setup to do this...hopefully you still have the paper work on thermostat... most heat pumps use the o terminal for reversing valve but rheem uses the b terminal
hope this helps out some repost with anymore probs...also make sure the switches are set to electric or gas whatever you have heat pump or not etc. inside thermostat
Check the circuit breaker(s) for the outdoor unit. Then set the thermostat to make the unit come on and see if the contactor pulls in. If it doesn't turn the fan switch from auto to on and see if the indoor fan comes on. If not your transformer could be shot. If the contactor pulled in on the outside unit check the capacitor for the fan and compressor.
no this is not normal. the fan should stop running when the thermostat is satisfied or when the heat pump goes into defrost mode. if it is running nonstop, there is a contactor that operates the fan and compressor that if it sticks will get line voltage to it. you would have to take the cover off of the outside unit and turn the thermostat to off. If the fan continues to run, you need a new contactor.
I believe the unit you are describing is a heat pump. Heat pump are great when the temperature isn't below 30 With low ambient temps. outside it is much more efficient and comfortable to run aux. electric heat from the heat pump.
Let's start out by your statement that the fan would not run, then you changed the contactor, not it won't stop running.
I believe, based on your info, here's what you need to do. Kill power to the unit. The 2 wires bringing power to the outdoor unit should be on the top 2 terminals. The 2 fan wires should be on the bottom 2 terminals. This is providing that the contactor is mounted Vertical. The could be an outside chance that the unit has a short in it and you are getting voltage feedback somewhere.
Take another look.
The fan is controlled by a blower timer board located inside the air handler, or on older units it has a relay called (of all things) a blower relay. If these items were at fault I doubt removing the thermostat would cause the blower to go off. if bad causing this problem the blower would continue to run even with thermostat removed.
But it is also controlled by the thermostat.
You mentioned that if you remove the thermostat it cuts off. There are 2 switches on most thermostats. 1 has Cool, Off, Heat, and Emergency Heat (on a heat pump stat) 2 The other switch has On and auto (it is for the fan motor only)
I believe because it stops when you remove the thermostat that the switch on the fan is set to on possibly. It should be on auto-matic. This way the fan motor only come on with cooling or heating. If in the on it stays on all the time. If this is the case just switch to AUTO.
Or the thermostat may be wired wrong. The G terminal is where the fan motor gets instructions from the thermostat. Make sure its on G at the stat and the correct wire at the blower coil is being used for the corresponding wire going from the stat to the blower for G. Don't confues G for green it could be any color. The terminals are not for color but it makes more sence to make them color - letter identified. On the other end soemtimes the wires are not colored the same so look carefully.
Also a whisker of a thermostat wire could be touching inside the thermostat and causeing the motor to run 100%. Look carefully at this and see if it has too long of thermostat wires stickinhg on out under the screws to where they may tough other things.
If neither things stop or show the problem and it deffinately stops when thermostat is removed the thermostat is most likely bad.
If this helps you 1 way to make the repairs your\self or helps you realize you need a technician please rate mne as high as you can.
If you have a standard thermostat the fan switch is for the air handler only. It completely over rides the thermostat for most settings. Now lets see this is what I'd expect: fan switch on Indoor fan runs all time Fan switch auto Indoor fan only runs when thermostat is set to cool or heat and the thermostat is turned up above room temp for heat or below room temp for cooling. In both of these modes the furnace blower comes on and stays on til the room temperature is satisfied. The outdoor unit only comes on for AC the out door unit will not come on for heat or the "on" setting on the thermostat. See exception 1 & 2 below...
Exception 1- (in a heat pump the out door unit runs in both heat and cool mode
unless it has emergency heat turned on then it will not come on outside
in the heat mode, and depending on the type of heat pump and furnace or
air handler it is). A heat pump thermostat usually has "backup heat" and an "emergency heat" setting switch on the thermostat. Exception 2 - On some thermostats they are made to cycle on the heat if the temperature reaches a preset temp (around 50'f usually but definitely by 40'f). This mode prevents freezing when if instance the homeowner is away or while the home is under construction. In this mode the fan inside can run but the heat usually comes on with it. Exception3 - On some electric furnaces the heating strips may be individually controlled and thus not all come on at one time. This may give the feel of no heat especially if the room is cold.
Now there may be other exceptions but Ive tried to give you a heads up on some of the most common ones. If you need more help please post more specifics about your unit/system as to for sure what switches are set to what setting and what is happening with each. My first though was that maybe your system is OK and you needed to know if the thermostat was working properly.
If this helpd you understand your problem would you please give me as hifgh a mark as you can. Thnaks for using fixya and good luck.
