Your combustion motor is the very first thing to cycle when theres a call for heat. Look at your access panel. There should be a LED status indicator chart. It will tell you what the flashing LED means and what your most likely problem is.

SOURCE: furnace starts up blower starts..nothing

Do you see the actual ignitor glow? You must be saying that you sanded the sensor. The ignitor, after the little inducer fan comes on will begin to glow a bright orange until the burner lights. If the ignitor is broken, you will NOT see a glow, and you may smell a faint smell of gas.

SOURCE: GE furnace pilot won't ignite

Check for 24 volts at the pilot valve on the gas valve, if there is voltage, take an amp reading, if you get amperage it's trying to work, see if pilot orifice is obstructed by webs etc. very common to see this.

Igniter isnt lighting


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.

Intertherm furnace model # MMHB-070ABHR-06 red light blinks two times


Number of flashes mean different things for diff models. The meanings of those flashes should be posted somewhere on the unit; usually inside front of the bottom service panel. Though you can't truly diagnose a problem by number of flashes they can give you an idea of where to look for a problem. There are a ton of videos and how-to's about furnaces on youtube by real service techs. Most modern furnaces have basically the same set-up and features so don't worry about your paticular brand; but of course that would be the best place to start looking. You could start here to familiarize yourself with your brand of furnace:

Hope this helps.

Ruud achiever 90 plus furnace will not start with door on.


I would try to check your return air first, making sure there is no blockage and that your air filters are clean. It almost sounds like when you take the cover off, you are pulling enough air into the system for it to run, but as soon as you close it off, it's not getting enough air flow, therefore, tripping a limit switch inside the furnace. Most furnaces will also have the codes for the flashing lights and what they mean on the inside of the door covers.
