Question about Heating & Cooling
My first thought is, if you have to ask this question, you should not be playing with your HVAC because you will likely hurt yourself. But if you insist; What does the humidifier require 120 or 24V? If it is 24V, then you take it after the thermostat at the relay that turns on the rest of the system. If the humidifier wants 120V, take it from the switched portion of the above mentioned relay. Your heat pump is 240V, so one side of the humidifier goes to the relay, the other side goes to ground, not the other side of the 240V return. If your heat pump is connected through a GFI, this will likely trip the GFI, shutting down your heat pump.

Go to page 12. 24V should be terminal 6 and A on the relay. 120V should be between B and ground on the fan motor. Before opening anything, turn all the breakers to the heat pump, likely 3 dual gang breakers. Have a couple spare automotive ATO 5A fuzes in case you blow one. Have an shut-off valve for the water supply. Please be careful!!! What you are doing has a high potential of hurting yourself or blowing up something in your heat pump, leaving you without heat.

I would check the house thermostat(and its wiring to the indoor unit), and if it's OK then check the heat transfer fluid diverter valve inside the indoor unit (should be sending the hot fluid through the big radiator (air exchanger)) until the surface temperature of the radiator is approximately 130 degrees F, then the fan control operates and the fan starts to blow hot air through your ductwork. My HTM is 26 years old and I've had many opportunities to "hone" its operation...

This is no doubt due to failure of the "hot surface ignitor". This device lights the main burners for your furnace, and they fail a lot. I strongly recommend the replacement should be done by a technician.

It is normal. Your house has to go down a couple more degrees because the heat pump is not working. You can solve this by rewirng you thermostat. Take off the wire that goes to Y and tape off. Then take the wires that are marked w and e or w1 and put the wires to yellow. Do not run ac with it wired like this. If you need more information please post me back

Look at your Thermostat wiring.
If there is a green wire going to the "G" terminal, disconnect it.
If it stops running, you have a bad T-stat.
If it keeps running, you either have a stuck fan relay or a low voltage control wiring malfunction.
Those are usually related to one of the safety switches having problems.
If green is not going to G, let me know, and we will determine which one is indeed the fan wire and go from there.
Remember, when you rate the solution, it closes further dialog, so only rate when you are satisfied with the discusion.
Thanks for visiting FIXYA!
