Probably a time delay relay fan switch not working.
Could be a bad low speed winding in the fan motor.
Set the wall T-stat for ON fan and see if it works.

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.

Sounds to me like it is going off on a weak high limit switch. With the fan on it will prolong the event but will not stop it. I would check all of the high limit switches. It would most likely be one close to the heat exchanger.

Nordyne furnace FEH017HA-04 the fan runs full force when the ac is on but half speed when the furnace kicks in


That is probably normal if it is electric heat to slow the air over the heating elements. Even some gas units do this. Check to see if the unit blower motor has wires for multiple speeds.

I have air coming from the vents but no heat. The furnace is 23 years old and I've never replaced anything in the unit. Best guess? GE Intertherm. thanks


If the thermostat is set on Fan and not Auto the fan will continue to run. If the fan control is bad or is set at too low of a setting, it will blow cold air after the furnace has shut off. From what I guess of your explanation, your furnace is not producing any heat and the room air blower runs blowing cold air. You may have two issues happening. Make sure your thermostat is calling for heat by setting it to a high setting. Inspect the thermostat to see if it is set at Auto. Go to the heating system and inspect it to see if it is heating. If you can't view any flames carefully touch the exhaust pipe and see if it is hot. If not, you have a no-heat condition. A 23 year old furnace may need some TLC so call a technician you trust. He/she may need to replace the ignitor or thermocouple to get it going. They will also check out why your fan is running when it should not.

The model of T-stat you gave comes up as a discontinued model on Honeywell's web site, but it looks to be a manual stat that type of stat would have to be wired with a summer winter switch with electric heat, allowing it to turn on the fan with a call for heat. If yours is a programmable T-stat you would need to select electric heat or in the installers set up change the default setting for fan from unit controls fan in heat to thermostat controls fan.

Intertherm E1EH-015HA FURNACE no heat


Sounds like a downflow electric furnace? If so it sounds like you have 15kw worth of electric heat, you might have a defective heating sequencer, witch is what they call a dual on one plate.
