Just moved into a new house that uses in-wall electric heaters. Sooner or later, we'll be switching to a heat pump, but until then, I need these as it's getting cold.
Our first floor has two heaters connected to one thermostat. One runs fine, but the other keeps shutting off requiring that I take the front panel off and push in the reset button.
If I reset it, place the cover back, it runs fine for about 10 minutes then trips off.
If I reset it but don't place the cover back, it runs just fine and never trips off.
What is the cover doing that could be causing this unit to keep tripping off?
I'm giving Ed the credit as his theory seems to fit the solution I came up with: I flipped the vent cover over.
The cover on it had all the fins pointing down. However, this heater wasn't the same as the other heater with the same cover...which seemed specifically designed for this cover. So, on a whim, I just spun the cover 180 degrees so the fins slanted up and the heater hasn't tripped since. Seems as if the upward fins allow more of the heat to get pushed out preventing the heat trip.
