There is a little switch on the circuit board. Look closely at the wiring diagram and it will indicate which switch to adjust. If not, review the operating manual for details.

My Payne furnace is NOT producing the desired heat anymore. Any ideas?


Hello, it could be shutting down on it's high limit switch due to a dirty air filter, dirty blower wheel, weak blower motor. Usually this would cause the furnace to shut down before it reaches the desired temp.

Hello, looks like you limit switch keeps opening because your furnace is overheating, Check your air filter and blower wheel to make sure it is not dirty and make sure you blower motor is moving at the proper speeed. Usually when air flow is cutoff the limit switch will open.

Have model MD300TGA with blower.Blower is set on auto but doesnt kick on.When should blower start up after room has reached desired temp. and heater has shut off?


There should be a limit switch and once the heater reaches the set temperature the blower gets signal from the limit and that turns on the blower. If you are not getting the blower until after the room is up to temp then it is coming on it may be the low limit is bad and it is cooling itself down on the high limit. If you are unsure of this please consult a heating service person, this is a serious problem that a trained service person should deal with. This can lead to a house fire!

My coleman 7900 furnace blower cycles on and off while burner continues to operate


I would look at fan limit switch. They are normally located in electrical cotrol compartment. If your are lucky you will have one thats adjustable. It would helpful if I knew is your home a mobile or modular home as they usually use a button type limit on fan and hi limit. It sounds to me like you may be having problems with fan limit which controls temp. that fan comes on . Often what happens is that switch scenses temp to turn on and then draws cold enough air on return air to shut back down until temp.rises again.If this occurs when unit first comes on or continues after burner shuts off you can get a limit switch with a higher temperature rating or one that has adjustable temperature range. Hope this helps you.Thanks.

Carrier Furnace infinity 96.model 58MVP060-F-18114. Furnace heats


Sounds like it could be your fan limit switch. Part costs about 20 bucks and is fairly simple to replace. This limit switch is a safety that prevents your furnace from over heating. Usually when your t/s is satisfied the blower runs for a little longer after the burners have stopped, and the reason for that is the limit switch. The blower is supposed to cool this limit switch to a certain temp. and once it reaches this temp it shuts the blower off. Yours is stuck:(

Limit Swith on Coleman Central Heating and Air


Sounds like the limit switch is not bad ...... its just doing its job. You need to determine why he furnace is overheating. Are your filters clean? Is your blower wheel clean? Is your blower motor running fast enough? It might be set on to slow of a speed. The blower motor capacitor could be bad. Are all of your air vents in the house open? Are your return air registers blocked? Is your duct work properly sized? Put a thermometer in the return air duct. Note the temp. Now stick the thermometer in the plenum. Note this temp.. Subtract the high temp from the low temp. This number should fall within the temp. rise rating found on the data plate inside the the furnace on the same sticker as th model and serial numbers. If your temp. is above the suggested temp rise. you have an air flow problem. If it is within the suggested temp rise listed then your high limit control should be replaced.
Good luck

Limit Switch


It is rare that a limit switch goes bad. It is a safety control. If it is shutting off your furnace there is a problem that it is protecting you from.
If the limit switch is shutting the unit down your furnace is overheating. Check the filters. Check for any obstruction in the blower assembly. Check to see if you can raise the blower speed. Make sure all registers are open in the house. Your evaporator coil could be obstructed if you do not take good care of your filters.
