Monitor heater

[Linda C]

My heater is flashing Lo on the display instead of the current temperature. I think I need a new sensor cord. As long as it flashes Lo it will not shut off so the thermostat is useless.

What can I do?

what model number is the heater. if the thermister is bad the display should read 42.

Your room sensor wire has either been cut or come out of the main board. If cut it can be but back together. It makes no difference which wire goes where. Tom
