Indoor blower won't shut off on heat pump


I would look to replace a relay that is not shutting off or replace the thermostat itself.

Fan does not stop


The assumption is that you are talking about the indoor fan....If so, check the thermostat fan 'on-auto' position and make sure it is in the automatic mode. If so, there is a possibility that the fan relay on the fan control is stuck in the closed position. If you have an older electric furnace, the first stage heating element could be stuck closed because the fan comes on with the first stage heat on many of the brands over 10 years old.

I have an intertherm electric furnace FEH-A020, with multispeed blower installed when A/C added. My problem is blower operation. at the end of the cooling season with fan set to auto operation the fan ran...


The model of T-stat you gave comes up as a discontinued model on Honeywell's web site, but it looks to be a manual stat that type of stat would have to be wired with a summer winter switch with electric heat, allowing it to turn on the fan with a call for heat. If yours is a programmable T-stat you would need to select electric heat or in the installers set up change the default setting for fan from unit controls fan in heat to thermostat controls fan.

The fan in the airhandler wont shut off.


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.

Fan running constantly in the house


Check t-stat and make sure fan is set to "Auto", that might be why fan is running all the time, or it could be a fan relay that is stuck closed. It sounds like you A/C is over charged or you have a bad high pressure switch, this was a common problem with this manufacture especially in the heat mode.

What position does the small lever on the right side of the T87 Honeywell Round T-stat need to be in to be OFF ?


The switch on the right side of the T87 is for the fan. Down is the auto position which will cause the fan to run only when needed. Up is the always-on position, used to circulate the air constantly. If you want to shut down all heating cooling associated with this thermostat you need to look at the switch on the left side of the stat. To the right is heating, center is OFF, and left is ac.

Weather king inside electric unit


He shorted the Transformer and lost all the 24v low voltage controls. This could have possibly been a loose wire in the T-stat or even a defective T-stat. It could have even been a reversing valve in some cases. Unit would only run auxillary heat bank in on position.

Intertherm air conditioner split unit


you need to know if the heat strips are energized by a contactor or relay as opposed to a heat sequencer. as a general rule the contactor or relay clicks shut as soon as a call for heat is made and the fan is energized by the stat at the same time . instant heat strips and instant fan. if the heat strips have a sequencer it may take up to 90 seconds or so before the sequencer heats up then clicks and puts power to the strips and the fan motor at the same time. the high voltage usually feeds from the strip side of the sequencer through the normally closed side of the fan relay. if you changed the stat and didn't switch the fan setting switch to elec, the fan will not be energized by the stat. if it is in the gas position, you have told it that the sequencer is bringing on the fan and of course it won' t if you don't have a sequencer.. this is tough stuff to trace even for an experienced pro cause its interconnected so dual fan speeds can't be energized at the same time. most likely you have a new digital stat that was not programmed correctly to bring fan on in heat. good luck
