The blinking light on your Coleman Mobile Modular Home Electric Furnace can indicate a variety of issues, and it's important to identify the specific pattern of blinking to determine the cause of the problem. In general, a four-blink pattern can indicate that the furnace has detected a malfunction in the limit switch circuit.
The limit switch is a safety device that is designed to shut off the furnace if the temperature inside the furnace becomes too high. If the limit switch is not functioning properly, it can cause the furnace to shut off unexpectedly and display the four-blink error code.
To troubleshoot this issue, you will need to check the limit switch and any associated wiring for damage or loose connections. You may also want to check the furnace filter and make sure it is clean, as a dirty filter can cause the furnace to overheat and trigger the limit switch.
If you are unable to find your model number online, you may be able to find it on the furnace itself, or you may need to consult the owner's manual for more information. It's important to follow the manufacturer's instructions when performing any repairs to your furnace, as improper repairs can potentially cause further damage or create safety hazards.
If you are unsure how to troubleshoot the issue or are uncomfortable working with electrical components, it is recommended that you contact a qualified HVAC technician for assistance.
There should be a diagnostic chart on the furnace door by the wiring schematic. If so see what the code reads for three blinks.
By the term "air combustion switch" I guess you are referring to the pressure switch. Most diagnostics blinking three times is just a dirty flame sensor. If this is the case the burners will light and go out within 4 seconds. If this is the problem carefully remove the flame sensor and clean gently with emery cloth, fine sandpaper or fine steel wool. Reinsert the sensor and enjoy your heat.
IF YOU LOST POWER WHEN FURNACE WAS RUNNING IT TRIPPED ROLLOUT SWITCHES AND POSSIBLY THE HIGH LIMIT . IN CENTER OF ROLLOUT SWITCHES IS A LITTLE RED BUTTON THAT YOU RESET . YOU CAN ALSO TRY FINDING HIGH LIMIT WITH POWER SHUT OFF TO FURNACE PULL BOTH WIRES OFF HIGH LIMIT AND USE PAPER CLIP TO JUMP BETWEEN THE TWO WIRES MAKE SURE YOU DONT SHORT OUT AGAINST ANY METAL WHEN YOU TURN BACK ON IF IT WORKS YOU NEED A NEW HIGH LIMIT SWITCH.
