First off hello to all those who read and post here. I am a newbie to
this group but I was hoping for some opinion from those with more
experience then me.
I have a Ruud gas pack furnace c.1996. About three weeks ago it started
making a horrific noise and stopped heating. If I turned off the heat
and just ran the fan it ran fine, so the main fan motor wasn't the
problem. I got a number for a freelance HVAC guy who told me the
draft-inducer blower was bad. I ordered a new one from
electricmotorwarehouse.com and he came out and installed it for me.
Presto! My heat had never worked so well. He showed me the old blower
assembly and it was corroded beyond belief. only about one fourth of the
squirrel cage was left, so I have no doubt that it was bad.
Then two nights ago I notice the house is a little chilly and check the
thermostat. I could hear the "tick" sound indicating that the heat was
supposed to be engaging, but the blower never turned on. When it was
working the inducer motor would start as soon as the heat was supposed
to engage I think. Again the fan is fine. The controls seem to be
working. The HVAC guy came out yesterday and said the new inducer motor
My question is, is this a common thing? Are electric motors sometimes
just bad and flake out after a couple of weeks, or do I have a deeper
problem? The guy who came out said the controller board looked fine (we
had the controller board replaced about two years ago.) Is there a rely
or something that could have burnt this motor out? The old motor showed
no signs of being burnt out. In fact it was still spinning even in its
horribly corroded state. This new motor just doesn't seem to be doing
anything. It's not locked up, if you spin it by hand it spins fine.
