I found the model number and specifics on a label on the side of the motor – the label says 71623861e. They sell the draft inducer motors online at a variety of places, including Amazon. It didn’t look too complicated to replace it and most comments said they could do it in about 30 minutes but one said it took 2 hours but the stated they were going very slowly.

There are a few videos out there on how to change the inducer motor.

Looking online, it seems other people have been quoted $600 plus another $240 for labor.
I have no idea if the $600 is for the part without labor or for the part and labor. He also said that I’m basically in for about $150 already. I asked how much the part costs, and he said $600 for the draft inducer motor. Our house has been in the low 60’s inside, but we are supposed to have some cooler weather between now and Monday. It isn’t freezing outside, but it isn’t particularly warm either. He sets a time for someone to come out on Monday – between 2 and 4pm. He comes back in and says the part is not in stock but it looks like they will get it on Monday – and today is Thursday. I figure this means that the office has one in stock and he’s waiting for someone to bring it out to our house. He goes outside and spends about 30 minutes apparently talking on the phone. Apparently when it fails, it will get hot. He feels the draft inducer motor and says it is really hot and it failed. The technician showed up around 3:15pm, takes off the cover, and says it smells like something overheated. They said they had a bunch of calls for heat being out but they could send out a technician between noon and 4pm. They called me back just before 8am when they opened. I decided it was time to call in the professionals and I left a message for our HVAC company we have a contract with. I was pretty sure there wasn’t any animal in there, but I had no way to check.
My pipes are pretty high off the ground and fortunately, the one for my furnace has a wire grate covering the opening. Reading for other problems that could cause this led me to read someone who had a dead rodent in their outdoor vent pipe. I tried it and unfortunately, it did not help my situation. I’d suggest just being careful not to blow too hard and damage the switch. For some people the fix lasts a long time, for other people, it at least gives them enough time to order a new pressure switch. I found a YouTube video with a solution that apparently works for many people – blowing in and out into the tube attached to the switches to “exercise” the switch and loosen up anything that is sticking. It turns out my furnace has two pressure switches and there are a few causes for the pressure switches to fail. None of the listed suggestions were helpful, so I resorted to look things up on my good friend Google. Looking at the panel schematic, it said that the problem is an open pressure switch and proceed to step F on the troubleshooting chart. This was a new one – two flashes of the green light followed by a few second pause, then two flashes again, etc. My Rheem furnace has an indicator light that will flash different codes based on what the problem is. I’ve had some success troubleshooting in the past, thanks to the internet. Yesterday the furnace stopped providing heat.
