Having problems with your Air Conditioners ?

No heat My 7500 zoneline will not provide heat consistantly. I can unpplug the main power source to the control boards and plug it back in, ,and I will then get heat. If I turn down the thermostat (80 to 70), then turn it back up, I do not get heat again, only cool blower air. Is one of my control boards bad? Thanks.


Answers :

It sounds like it could be the tstat itself. Unless you use a voltage meter to take some readings it's hard to determine if it is a board. The best thing for you to do is remove the tstat from the system and manually operate it with a jumper wire to try and recreate the problem. If you can't recreate it, by manually turning on the unit, then it's the t-stat and if you can then it is the board. This happens with t-stats occasionally. Good luck and I hope this helps!

We have model # 58SXA080-JG Gas Furnace-the fan is not turning on-heat is not coming thru the vents. We had the control unit/circuit board replaced yesterday.

I have a Heat Controller EKTH15-150J PTAC. Of lat,e toward the end of winter here in southern Missour,i the unit while in heat mode has been randomly blowing cold air. Often you can shut off the unit and let it sit for awhile and when you turn it back on it will come up heating again. A couple of years ago I replaced the control board that had been killed by a lightning induced power surge with a RSKP006 control board kit. It has run fine since, until the last few months. Sometimes I can pu

When you changed the motor, did you change the capacitor? If the motor hums, but doesn't run, the capacitor may be the problem. Also, about a week or so ago, I changed a furnace blower and capacitor only to have it shut down again after 2 days. I ... Amana Air Conditioners

I have a honeywell PA404A pressure control switch on my home gas steam heating system. I'm having a problem with the switch turning off the system. It will only come back on if I turn the top screw all the way out, then back down to approx 5psi. At this point the heat will turn on but when the thermostat shuts down the system it will not turn back on when calling for heat unless I adjust the screw again. Also, the switch will only turn on the system when set at 5 on the dial on the inside. Any i


This may be caused by accumulation of sludge in the steam trap (the looped tube that connects the pressuretrol unit to the boiler). the sludge restricts the pressure from reaching the diaphragm in the pressuretrol unit. So it gets a false reading. ... Air Conditioners

Count the number of flashes and consult your manual as to what the flashes mean. The blower access door may show the faults codes. What you probably have is a contaminated flame sensor or maybe a rollout switch tripped due to rusty burners or air res ... Air Conditioners

I have a remote comfort control with 3308448.004 relay board. Press Heat button to turn unit on and it does NOT turn on. Have 115VAC to the relay board and have 12VDC to remote control reciever. Sounds like the remote control reciever is bad?? Can I switch my system to the "wired" control system without changing the relay board? I assume it is possible that the relay board is also bad. Is this a common fault with these units?

When call for heat on model # WGPH-10eamer serial number DF5D302f419801914 the furance goes throught the cycles, the burner comes on and cuts off after 8 seconds. The flame censor was changed and the power was shut down for 30 minutes. It was then turned back on and the furance worked for a while and then repeated the problem. On the control board-there are 3 lights. 2 greens and sometimes the yellow one. Thats when the yellow is working right. The yellow one does not come on that much.


It could be the control board, But before I would replace the board I would check to see if the flame sensor is not touching the burner and shorting it out. Also check the flue make sure it is open. This has a combustion blower on it and a proving pr ... Weather King Air Conditioners

I have a multifuel stove which runs my central heating system from its back boiler. When it gets really hot there is a loud clicking and knocking sound from the rear of the stove where the thermostatic control is. The noise stops when I turn the electric pump off. How do I fix this please?


That clicking and knocking noise you hear is called cavitation. It's when the bubbles of steam are cooled down rapidly and implode upon themselves. Cavitation is not a good thing to have in a boiler as it can cause dramas. This cavitation is more ... Air Conditioners

I turn the thermostat down at night. When I get up in the morning I turn it back up. The heat kicks on for a minute or two then the unit starts blowing colder air. If I turn the thermostat to the OFF position, wait until I hear all blowers stop, then turn it back to the ON position, it will start blowing HOT air again. Some times I have to perform this cycle 3 times to get it to keep blowing hot air. Any ideas as to what is shutting the furnace off? Thanks, Wayne

I have an NewAir 12000H Portable Air conditioner with a heat pump. The problem is that the heat pump no longer seams to be working. The desired temperature is 79 degrees. the unit never gets above 75 degree. when it actually gets that high it because my heat from the house has turned on. once the heat goes off then the unit goes down to 72 degrees and stays there until my heat comes back on. whats wrong with the unit? is there anything that i can do?


It sounds like the actual control module, the "brain", of this heater / air conditioner has failed and can't sense when to kick on the heat any longer. Have you tried just unplugging the unit for a good 5 minutes minimum and seeing if it will help " ... NewAir Air Conditioners

With unit set to air conditioning, the controller board will not turn on the blower motor and the cooling coil freezes up. McNutt tells me the controller board is kaput and they want $550 for it. In the meantime they have jumpered over the controller so the blower runs constantly. Was hoping someone might be able to tell me where to get it for less.

We have recently bought a house with Vulcan ducted gas heating (no pilot light). When the system comes on it produces plenty of heat so I don't think there is anything wrong with the unit itself. Frequently, however, it reaches the set temperature, turns off, and then will not come back on even if we press the on/off button. The only way we can get it back on is to cut power to the house and then press the on button. That would suggest that there may be some kind of program set, but since

You could possibly have an ignition problem. The controller will go into a lock-out condition if flame is not established. Turning the temperature control down and then back up may be serving to reset the control system so it tries again. ... Honeywell Air Conditioners
