Last Friday, we discovered that our heat pump was not circulating air through the house and there was a hot electrical odor. We turned the heat pump off and got our auxiliary heating source going – our fireplace, which has an insert with fan.
We were able to get a technician to come out on Saturday, but when he turned the unit on, everything worked properly and none of his measurements on the circuits turned up a problem. He did discover that the ducting on the outlet of the unit had become partially disconnected, so we were losing heat under the house. He fixed that, which made a huge improvement on airflow.
Around 4 PM today, Karen noticed that there was no air coming out of the duct under her work table while the heat pump was running. Before turning the unit off, I wanted to check it a little closer to have more info for the tech. I also took the following video to show what it’s not doing.
The fan that circulates air through the house wasn’t working. The arrow in the image below, from the video, points to the stationary fan blades. If the motor was working, the blades would have been a blur.
We’re in a very cold period, that’s going to be a bit colder later in the week. While the fan does work after the system has been off for a while, we’re not going to leave it running in auto when we’re asleep or away, so we’re hoping the tech will have a replacement motor tomorrow, before the really cold air gets here.
Isn’t amazing how things will start acting up when you really need them?
