Re: New post still problems

Hi,

Are you also trying to remove air conditioning from this unit during the rewire? Do you have an original wiring diagram to follow? If you need a wiring diagram for a heat-only furnace, doublecheck your model number and send me an e-mail.

Thanks,
Mark

Re: Coleman 4000-7121C Roof Jack

Hi,

I'll have to get back to you on that. The DFAH is not listed as one of the furnaces you can use the 4000-7121C roof jack with.

Re: Centrifugal Switch Stuck

Hi,

The centrifugal switch is built into the booster motor. Once it sticks you have to replace the motor. Part number for your furnace is 7990-317P/A, which you can see and order here: http://www.aberdeenhomerepair.com/store ... ster-motor

Re: Deluxe Blend Air II Humming noise

Hi, The model number you gave was for the Deluxe Blend Air system, which is an add-on fresh-air system to your furnace. To find the model number to your furnace, remove the doors and look for a tag. I'll be able to easily tell you which transformer you need once I know the model number. We do sell t...

Re: EB15B

Hi, Yes, you have a Coleman. Many times when heating elements don't come on, the fault is a defective sequencer. The sequencer for your furnace is part # 3115-3571. http://www.aberdeenhomerepair.com/store/product/2311/3115-3571-sequencer You can check the heating elements for resistance. Shut the po...

Re: Heater is blowing cool air

Hi,

For starters I would look at the burner assembly and see if anything is partially blocking the main burner orifice. If it's clear, then do some pressure checks on the gas valve. Might want to call someone out for that one.

Re: Furnace not staying on

Hi, If the pilot stays lit, your thermocouple is fine. When the burner shuts off, does the blower shut off at exactly the same time too? If it does I'd say a limit switch is faulty. If the blower shuts off a few seconds later, then it's possibly a faulty fan switch. This is your limit switch: http:/...

Re: changing propane to electric furnace

Using propane or electric really depends upon which part of the country you are in. Some rural areas have darn cheap electricity.

Re: Problems once again

Most likely you have an a/c control box mounted on or near the blower assembly housing? If so, do you have the type that contains switches and relays, or a circuit board?

Re: e2eb-012ha heat and ac both at the same time

Does your unit have a separate a/c control box normally find on the motor housing? If so it sounds like there's a relay inside there that's giving you fits.
