I tried to turn on my heat this past weekend and it did not work my air works fine but the heat does not.the furnace is hot but the fan will not blow. It is a nordyne intertherm model e2eb-015ha in a modular home. Everyone I spoke to says it is quite possible the blower relay or fan and limit switch I just need to know wheree these are located on this unit to test them I can not afford the $150.00 service call can anyone help

Look on the blower door for your wiring diagram and follow that to find the blower relay or any other parts you want to check. Also in many units the sequencer acts as a blower control device.

Here is a wiring diag

If you have the A/C,off and heat switch located on the furnace this is a diagram for you.

Gas or electric furnace? If gas ,I may be able to help. If electric, sorry , I'm no help.

It is electric. I posted the diagrams for this person but you have to know how to use them.

Exactly right hvac. You must know what you are dealing with when it comes to electric furnaces. I could fix your furnace if I were there but I wouldn't recommend dealing with this kind of voltage by yourself, unless you are indeed knowlegable of such systems.

If this system requires a fan belt then maybe it's just a fan belt.
Turn your system off and check the area of the blower motor. If u see a broken belt then that is the problem.

Nordyne never used a fan belt in there units. Take another guess.
