Unknown heater, ~200W, runs for 3 minutes, comes on 3-4 times a day


#1

Doesn’t appear to be associated with my kitchen fridge because it kept running when I unplugged the fridge. My garage fridge doesn’t have a defrost function.


#2

If you have central air conditioning it could be a crankcase heater https://en.wikipedia.org/wiki/Crankcase_heater.


#3

Good thought! I didn’t know these existed. I will test it out by cutting power to the outside unit the next time this heater is detected.


#4

For what it’s worth, I didn’t think it was associated with my refrigerators either because of the same reason. Which is also why I had a question mark after my garage fridge (separate device discovered) because of the same thing. It wasn’t until we had the whole refrigerator unplugged for a day or so that I noticed I didn’t see either the garage fridge or the mystery heat.


#5

I have this same problem. Mine shows up using about 400W and I have no idea what it could be.


#6

Almost identical experience here… ~180W per cycle. Eliminated the fridge & electric part of my HW heater by killing the breakers to them. It’s not a heater either (I live in Florida… we don’t know what that is yet at this time of year). Convinced it’s not a heat device but can’t figure what it could be.

Sounds like ice maker cube heater… warms the cubes up enough for them to be ejected from the tray.


#8

What about the heater on a water dispenser?
