sounds like safety switch not allowing it to run without cover in place.

by igniter I assume you mean the thermocoupler. are you turning the control button to run after you light the pilot light? Normally when those furnaces quit it is the thermocoupler that has quit. Get a new one and leave it in the furnace compartment as a spare.

either the heat strips, fusible links on elements or sequencers.

Furnace burner and heat element are not the same. I think the fan time delay, a sensor that turns the fan on when this sensor senses heat, is shot and needs replacing, for a furnace type heat ( gas heat)

intertherm units were used in many mobile homes. you can google mobile home supply
companies and should be able to find the replacement. Hope this helps.

The best thing to do is buy a washable horsehair filter from home depot and cut it to fit. They are green in color and you cut any size you want. They slide in the door of a gas furnace or along each side of the A coil in an electric furnace. That is your best bet. Most of the time the furnaces comes witha washable filter and it is thrown away after afeew times. Rus

OK so its an all electric furnace no gas? I cant think of anything clicking on an electric furnace except the sequencers or the safety switches.

If this is whats your hearing then the fan should definitely be running.

Feel carefully around the fan motor (I assume this is in a mobile home). See if you detect any heat coming around the blower area close to the fan motor. If so the fan motor may be at fault or one sequencer may be out (the main one of course...) the thing is can you get the fan to come on by turning the auto switch on the thermostat (or if older model the Auto On switch on the furnace) to ON? If so you can "limp by and have heat til someone either checks it or you can go on deeper into it. but to go deeper you'll have to let me know you know where the elements are and that you have a volt meter. and feel comfortable using it especially on HOT wires.

Is this a 120v motor, or 220v? If you checked for power, I assume you kind of know your way around a meter. When checking for power, don't check to ground, check the line. You could have power going in, but unless its going back out, completing the circuit, or missing a leg, in 220v case, it still will not work. Also, most heaters have some sort of delay, so after you hook it back up, and the burner heats up wait a few minutes for the fan to come on.
