Intertherm model e3eb020h electric furnace won't start just hums

The starter board controls everything. Pull it out, find a replacemeny on the internet. Make sure the power is off.

Check fan bearing.

I appreciate your post, Mike!

Based off what you have described your Frigidaire washer motor will hum and not start. In order to test each component you would need to have the proper electrical equipment. I would recommend contacting a professional technician for proper repairs. They will have the necessary equipment needed to complete your repair. Hopefully this is helpful. -Matt

humming could be a body panel or metal to metal point that came loose and just needs secured in the furnace or ductwork. could be an electrical issue that you may or may not be able to find with the doors off and trying to locate where the hum is coming from. it may go away when a panel is removed because it night be air sucking through a loose section of the door. the question is vague but I would press around while its running to see if it subsides. as always when its running with the panels off electric shock hazard and arc flash can occur causing bodily injury or death that's why they have the door switch which will cause the unit not to work with the door off. you can tape this switch to test the furnace but be very aware it is done on your own and I cant tell you it is ok to do this if you have no knowledge of electricity and its dangers. this is only for you to possibly find a hum and not press around on electrical components.

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.

Unplug the ignitor and check it for continuity. If it checks good see if it is getting power from the board.

First thing to check is to see if you have electric out there. The hum is probably the 24 volt relay that is telling the a/c to come on. The 24 volt relay gets it's power from the indoor unit.

when was last time furnace was serviced --air filter change burner area cleaned vacuumed the hum can be a few reasons ---fan bearing need service [ oiled ] fan bracket bushings damaged or loose --burner out of adjustment burning improper etc these are a few

it was the thermstat i replaced the thermstat
thank you

That blinking yellow light is an error code. If you look behind the main cover there will be a wiring diagram and error code chart. This will give you an idea what the problem is.
