If the sensor knocks the unit off and the the fan keeps blowing without a flame ,the limit (the sensor is a limit comptroller that turns off flame @ a set temp and allows the fan to run until the heat exchanger cools to @ set temp) has out lived its lifetime and needs to be replaced.the button is a manual reset that once reset would allow the unit to continue to run flame and blower at the same time after having been set once, if it is an ongoing problem and needs to be reset more than once then replace the limit control (sensor) in kind. (With the same mode and set-points for the limits)

The reset button near the ignitor is a high temperature limit safety switch. When the furnace gets too hot and the manual reset limit switch is tripped, it most likely goes into a 'safe' mode where the gas control is locked out electronically and the blower is made to run continuously to rid the heat exchanger of the excessive heat. This will continue until the reset is pushed and the power is cycled off. It will remain an endless cycle unless the reason for the overtemperature condition is not corrected.

Your furnace 'temperature rise' is getting too high due to a lack of air across the heat exchanger for whatever reason. Some of those reasons could be a restricted air filter or a blower motor that's cycling improperly on its internal winding thermostat. You could also have a dirty air conditioner 'A' coil (evaporator) on top of the furnace restricting the air flow. Nevertheless, you are going to have to have it serviced by a reputable service company's technician to correct what's wrong.

Coleman Presidential Furnace 6806A842 heat switch pops then cool air


Make sure all vents are open and filters are clean. Likely an air flow issue but possibly, though unlikely, both switches are bad.

You are over heating because of dirty filter, coils, or bad or collapsed ductwork check return especially. on the units data label there should be a max and min temp rise this is the difference from incoming and outgoing air through the furnace. Check this.
or it could actually be a bad switch.

I would be looking at the heat exchanger. They are designed to have the heat from burnt fuel flow thru them. Cracking or pin holes will let the super heated air into the furnace interior and in there you have some over heating protection some look like buttons, older they look like an external thermostat, and these get the hot gas from the burners and trip then the furnace shuts down. When the furnace comes on again some times the blower will come right on because the sensor says hey this thing is hot when in fact it isn't. This also can and if bad enough will cause carbon monoxide poisoning, please inspect this closely or have a professional look at this. There is no price ever to great to replace a human life.Sorry probably not the answer you wanted but better safe than sorry!

Flame sensor needs to be cleaned. turn off the furnace power switch or breaker. pull the flame sensor located in the burner runner section of the furnace. It will be easy to locate because it has 1 wire running to it. pull the screw being very careful not to harm anything else. get the sensor out. inspect it for cleanliness. clean the sensor with light grade sand paper gently. re-install the sensor plug the wire back on. restart your furnace and this should fix the problem.

The fan limiting switch is acting up. It should stay running until lower temp is reached. It will cycle until the temp stays below or at the low setting. Limit switches are adjustable.

Heat temperature issues with Goodman GMP 100-4 furnace


69,000 btuh is adequate for a 12-1400 square foot house.
Otherwise, your thermostat simply tells the furnace to cycle on/off.
If it calls for heat and does not come on, the problem is with switches and relays within the furnace.
Your setting the temp higher only causes the other parts to keep trying until they finally light and heat.
This is based on your information saying it will cycle on and blow cool air--not hot air.
You will have several temperature variations from floor to ceiling.
You probably have ceiling vents as well.
You need a technician to verify the rollout switches, fan relay, inducer fan etc. if the furnace is not firing everytime you call for heat.

(HVAC) Furnace Not Igniting Quickly


Make sure a back draft in the flue is not happening. Wind can blow it out until the flue heats up. The flame sensor may not be close enough to the burner flame. It may be weak and need to be replaced or if its an optical one it may be dirty and not see the flame very well. Its not wasting much gas but it puts extra wear and tear on the gas controls, is noisy, and, as you said, blows cold drafty air. A gas control system that has issues of any kind is not real safe. It needs to get fixed.
