If you can explain where each wire from the motor goes I might be able to help. This way were on the same page. You may have 2 speeds comming on at once. Use an AMMETER to see if your running over amps and be sure you check it with the blower doors closed and clean filters all these can affect correct ammeter readings.
Other wise remove all wires (except the one going to the normally closed contacs on the fan relay, and the 1 going to L2 (usually called common) and the 1 or 2 going to the run capicator this may;leave with 2 to 4 wires. Tape them up sepperately and try it again. If it improves and workd mor correctly youmay have a bad relay. If it dosnt you may have a bad relay or sequencer depending on how its wired.

I have a 1987 Intertherm FEH-015HA electric furnace. The issue I am having is that my blower will not shut of unless I pull the disconnect. My thermostat will operate the heating elements like normal,

You most likely have a bad fan limit / cycling switch. If you kill the power to the furnace see if you can trace the wires from the motor to where the connect to the switch. It looks like a round button with tabs sticking out of it for the wires to connect. Mark down where the wires were connected and take it to a HVAC business or furnace supply house. Be sure to have the model off the furnace with you so you can get the correct parts.

How to replace Intertherm M1 Combustion Blower Assembly on an Intertherm M1MB 070A BW Gas Furnace Series #m1D020401209? I think this is the problem. The furnace squeals when turned on and it seems to be...

The combustion blower is easy to replace. You may be able to prolong the life of the motor by applying lubrication to the shaft bearings. If the motor is too far gone then replacing it is the only option. Just remove the screws that mount the blower case to the heater, disconnect the wires and reverse the steps to install a new motor.

My intertherm furnace (old model) has recently getting quite loud and clunky during its heating cycles, sound like the blower maybe??

Your blower motor has several speeds to it and by the problem you are having it sounds as though the blower motor may be going out. The motor has a slower speed for the heating cycle and since you have the noise in the heating mode I suggest having the blower motor changed as soon as possible since it could cause other problems in the heating section of the furnace( possibly burning out the high limit switches). Good Luck on your repairs hope this helped

My Intertherm furnace will not shut off, the A/C cycles, but the blower runs unless I trip the breaker. I have replaced the t-stat.

It could be a couple of things; since you've already replaced the thermostat it could also be shorted wires from the thermostat to the furnace, or a siezed relay that controls the blower motor.

A miswire

The blower is smoking because you have it hooked up to the same wires you've hooked the electric coil to.  That coil runs on 240 volts.  Those wires are typically red and black.  The motor runs on 120.  One of the wires should be shifted to a neutral (white wire).  Assuming the motor is still alive...this will fix it.
