Hi Robert! Thanks for checking in. I am not having a problem since we haven't had any power outages, but I was wondering if you had any answers to my questions/theories above. We won't run the furnace unless we are home, or awake!. We still have the issue of the pilot going out when the furnace shut...

Furnace model #7710-856 Presidential II The furnace was running while there was a power outage. Within a few minutes, I noticed a bad burning smell coming from the furnace (filled the house actually :(~ ), and the furnace doors were hot! I immediately shut the main gas valve off and the gas valve, a...

Hello, I am not an HVAC expert by any means, but I had a similar problem, as my booster motor ran and ran (I have the same furnace as you). It turns out that the centrifugal switch (inside the motor) was bad. I replaced the motor (you cannot replace just the switch in this unit), and that solved the...

Thanks, Robert. I will check the above things.

Also, I notice the pilot has a split flame, and from what I read could be from a dirty pilot tube? You did mention that, so we'll go from there.

I have the same problem. I am just going to buy an entire exterior panel, which costs about $64. I am in Michigan, too.

Hello. Furnace model #7710-856 Presidential II Well recently fixed two problems thanks to this site (that I wrote about before...the booster motor and the crossover duct repair) so now furnace is blowing heat, but now we've come across another problem. :( (sigh) The pilot seems to stay lit the entir...

Thanks, Robert! Much appreciated, as always!

We t...

Hello to all again. I need to clean the A-Coils in my furnace for the air conditioner. They are packed with dust, unfortunately, and I am sure that's why I wasn't getting cold air through my vents. :( Anyways, I have a metal cover to seal off the a-coil area, and it has a small window on that cover ...

I have a few questions re: the draft inducer/booster motor, so I thought I would combine them all in one post (hope everyone doesn't mind). I have a Coleman presidential II model, and the motor p/n is 770-8314 (the approx 8 inch cylindrical black motor). 1) Before I call a repair man out, I wanted t...
