    if there is dirt on wheel just clean and should take care of. no way to repair if wheel is out of balance. have to replace

  • KEVIN LECHELT Feb 14, 2012

    make sure you shut power off before putting hands any where near compnents, could start and hurt you. if you don't know how to get wheel out just take a vacum cleaner with a brush on end and vacum good. might take a lot depending on amount of dirt.

SOURCE: fan keep,s blowing

Your thermostat is calling for blower, your fan relay is stuck, or that model had a time delay blower solid state board on it which had the blower relay on it, and it could be bad. I would turn the power off to all of your system for a few minutes and see if this could make something happen.

SOURCE: 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.

SOURCE: Intertherm

Is the contactor engaging? Make sure it is getting 24v. If not, check the low pressure safety, outside thermostat (if you have one) and the defrost board. Follow the low voltage from the thermostat to all these controls, up to the contactor. Check the thermostat too. If you need a walk through I can help, if you have a volt/ohm meter.

The unit will come on in house but fan is not on outside you can hear it clicking like its trying to and blowing warm air

Sounds like you need a new Run capacitor or hard start kit (includes the capacitor), but you should have it checked by tech

Intertherm furnace burner comes on, but blower does not. If I turn thermostat off then back on until it clicks the fan will then come on. It does not do this all of the time, just now and then.

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)

I have an Intertherm split unit A/C and electric heat I need a ladder diagram for the indoor fan relay and I also need to know which part number it is my intertherm model number is e2ebo15hb any help would...

Hi, the schematic would be in the indoor unit, but I am assuming its gone since you are looking for the ladder schematic for the heat strips and fan control. You might try this number for a schematic, 1-888-441-6942, Route A/C and they may be able to help you on this diagram. The number you are showing does not look like any model number at all. For both the indoor and outdoor units on the Intertherm, would look something like this...., P3RA-024k for the model number, and the serial number would be right below it. Both should be very easy for you to locate. It is very hard to find schematics for units once they are gone, as some tech's like to take them off units to go home and try and study them!!, unreal! Makes it hard to troubleshoot when you need it. Try to find numbers like I have noted, and call this number as they will answer questions you may have concerning yours. I hope the best for you and would like for you to rate me, as I know you will be kind. Please keep me posted on this as maybe I can help you solve this fan relay problem you have?

Where are the filters located on the Intertherm heating and cooling unit that comes in mobile homes ?

There are a couple of places to start looking.......the first place is in the return grille. If it is not in the return grille, then the filter should be in the Intertherm unit itself.......look for an access panel marked "filter".

Intertherm propane furnace makes popping sound when running

It sounds like you have a possible hole in the heat exchanger. Turn the heat off and turn the fan on. If you feel any air coming back out of the heat exchanger, you have a hole. A yellow flame is not a good sign. I would even consider having a service professional come out and take a look.

Heating problems

It sounds like the unit is going into a defrost cycle, which is normal for heat pumps and means all is working ok when it gets around 35 or colder they start to do this more often when the red light goes back off , the outdoor fan should come back on. You may also notice steam (may look like smoke) coming from outdoor unit. Is that what happens??
