The sequencer allows the furnace to use only a portion of the available power in portions rather than all at once. The electric furnace consumes massive amounts of electricity to the extent that overloads aren’t uncommon. The circuit breaker will trip without hesitation in case of overload, shutting down the furnace in the process. Have you ever come home, switched on your electric heater, and instead of the unit starting to heat up, it instead trips the circuit breaker and goes off? It controls when to bring on the electric heat elements in sequence along with controlling the blower motor in the heating mode.
How Does the Furnace Sequencer Work?
If there is an “i” at the end of the lock, your thermostat is, in fact, adjustable. If there is no I however and you determine that you don’t have a calibration lock. Switches with several poles, generally have multiple, alike switches which has a dotted line intersecting the center actuator. Use an electric test to make sure that it’s indeed off.

This box is labeled blend-air and it’s function is to bring in fresh air. If there’s a problem with the blend-air unit, a red light will flash and you may hear a beep. The unit should have a switch to shut off the beeper so it doesn’t drive you nuts.
How Do I Know if my Furnace Sequencer is Bad?
Although this one didn't light anything and when I went to the burn mode the pilot light just went out. Fortunately, it only cost me about $50 to learn about resetting the limit switch. The exact same part number cost $25 from one store and $95 from another, so it pays to shop around. That switch was back ordered, and took so long to arrive that it was summer when it finally did.
Be sure to rinse and let dry before re-installing. If you have a foam filter and have trouble locating a replacement, you can find one here. If the blower does run when you move the fan switch to ‘manual’ or ‘on’, then the problem most likely is a faulty temperature switch. For optimum performance and safety of your furnace, you should never guess at the anticipator settings. Always refer to the manual or contact the manufacturer. You may also be able to get the anticipator settings by looking at the gas valve for the amp setting.
Mobile Home Gas Heater Maintenance and Troubleshooting
So unless your gas cock is defective, or you opened it too fast when you changed out the pilot. Thank you so much for showing where the reset button was at. It had been raining all day yesterday into the evening and the power went off 2xs.
In this case, they had the proper switch on their truck anyway, so it wouldn't have mattered, but of course, it could have. These furnaces are way over engineered or shall I say imagineered!! Why not keep things simple moving forward on the newer models only makes perfectly crystal clear sense right. The furnace does give us codes which we’ve relayed to the service technicians but still causing us stress. Please fire all your engineers and replace simple minded people the world would be a better place.
How Your mobile home Furnace Works
If the reading is zero or considerably higher than 20, you should continue with electric furnace sequencer replacement. If turning the thermostat off doesn’t shut down the furnace, then locate the breaker in the fuse box or the main on/off switch on the furnace and switch to off. You should find a gas shut-off right in front of the furnace. The problem of not shutting off could be anything from a short in the thermostat wires to a bad gas valve so its best to let a qualified technician troubleshoot and repair. If your furnace has a fan control, it may be adjustable. But for the most part the temperature control switches are non-adjustable and are to be replaced if found faulty.
Fortunately, there is a switch on the thermostat to turn the fan on manually, so that's what I did, and we survived the heatwave. In this case, the light was flashing four times. If your blower does not shut off and it’s not blowing cold air, then that means the burner is still lit.
Reset the circuit breaker that switches power to your Coleman furnace if you are not sure what happened. These tips can get your home feeling cozy again in no time. The flame sensor used to detect whether or not a flame is present requires attention.
To stop the furnace, first try turning down the thermostat. If that doesn’t work, then turn the furnace OFF at the thermostat. First the burner will shut off followed by the blower. If your furnace shuts off when you turn the thermostat to off, a possible cause is a malfunctioning thermostat and replacing it should fix your problem. Since thermocouplers are so inexpensive, replacing it and cleaning the pilot light should always go hand in hand. With the gas valve on and a watch in hand, blow out the pilot light.
