    What is the brand & model# is it electronic ignition or standing pilot. Is it 80% or 90% effiency. How old is the furnace. Have you installed a new type of filter this year. How long has it been since it was last cleaned. Sounds like furnace needs cleaned if you have to reset thermostat to start again. It also could be the thermostat.

Check all of you wire connections. If they are all clean and secure you probably have bad board. Just because the circuit board is new does not mean that is good!

Coleman Evcon furnace blower runs w/ no call for heat. Temp is 5+ degrees above thermostat setting. (Programmable tstat)


When you say door are you referring to the front door or the furnace door? If the unit kicks on AND off by itself I would say it's in the tstat or the tstat wire. If it were internal I would think the blower relay or heat contactor/relay were getting stuck AND THE FAN WOULD NOT TURN OFF until you flipped the breaker. Good luck

Why do my honeywell thermostat blow cold air?


Either your fan Tstat setting is set to "on" instead of "auto" or your furnace is going off on a limit switch when this happens it automatically runs your fan for safety reasons. Check your Tstat setting then check and change your furnace filter if neither solutions work time to call a pro.

When i turn the heat up sometimes it takes a long time for the gas furnace to start ..why?


Watch your furnace when you turn the thermostat up...make sure to record everything that it is doing. If you have an induced draft, forced air system, then the heat sequence of order should go like this... Initial call for heat from tstat, Inducer vent motor turns on-pulls in the pressure switch, circuit board sends power to igniter whether it is spark or hot surface, then gas valve opens. Flame sensor senses flame, burner stays on, and blower motor kicks in to heat the space. If you notice any variance from this, then something needs to be checked by an HVAC Service Tech.

Heat....Furnace will not start up worked fine last year it is getting power... I can hear I light hum in the furnace but it will not start it process


If its a high or mid efficiency furnace most of the time the sequence of operation goes as follows: tstat calls for heat (R&W at tstat ) ventor motor starts, pressure switch closes, spark or hsi lights pilot or main burners. main blower motor comes on. From your description of a humming noise it sounds like maybe the ventor motor is seized.

Reset switch on furnace to make air contitioner start


I know what you mean. Not a lot of companies around here care to work on mobile homes. There is a safety on that unit that may or may not be a reset. Normally it will have a small red peg in the center to push and reset. Some don't have a reset though. Look for a small, flat safety, it should have 2 wires. And it may be hidden. As if 2 wires just disappear behind the blower assembly. Check for voltage to it, and across it. You can find volt/ohm meters for $10. Chase or follow the signal from the tstat. R comes from the tformer and powers the tstat. Tstat closes and sends a 24v signal through Y and G in cooling. Y should go from tstat to indoor unit, and to a terminal block or wire but, then directly outside to outdoor unit. G comes from the tstat to a terminal block's (g), then to the auto,off,on, then to a switching relay's coil. This coil closes and allows line voltage to pass through powering up the fan. So at the indoor, with 1 lead connected to common with your voltmeter set to AC volts, use the other lead to follow these paths. Or keep calling companies to find someone who will work on them. Electricians will not work on HVAC equipment. Even though it's all the same principal, source/line/load. Be safe!

If you have gas furnace, the outside unit will not come on unless you have dual fuel/ gas and heat pump. If you can look at wires in thermostat, if you have no wires going to O or B then you don't have heat pump. Normal tstat wiring for gas furnace and air conditioner. R,W,G,Y and maybe C.

sounds like you shorted out the heat anticipator in the tstat. try jumping red to white at the tstat wiring terminal and have a friend stand near the furnace to see if it cranks up immediately. if it does the problem is more than likely in your tstat. be sure to blow out any dust in the workings of your tstat. this is 24 volts and shouldn't hurt you but try not to short it out to the common or other wires.

On a Trane furnace the fan realy must energize before the electric strips will come on. On the thermastat. See if there is setting for electric heat. This will bring the fan on and the strips should come on. First just turn on your heat and and turn fan to on postion if it works you need to set tstat to electric heat mode. Most of the time there is sswitch in the back of the stat that says gas elec. Turn to electric. Rus

Ruud heat pump high pressure cut off problem


That's going to be in your installer configuration. Check and make sure the G terminal has a wire connected to it at the tstat , and that connection it tight. In the configuration menu, make sure it is set for a heat pump, elected heat. It seems to me that the tstat doesn't know its connected to a heat pump. Should be able to locate aodel # for tstat on the back of it. And ask Mr. Google for a manual, if you don't have 1. Hope this helps!
