I am replaceing a King PAW2422 "pic-a-watt" electric heater. Old heaters was both "dead", one died 1 year before the other...sort of...
The old ones looked "burned out", fan was sticking and they were at least 10 years old.
Now I bought 2 brand new ones, and after installing the first one, wired for 1000W (orange), like the old one and it is still not working.
The thermostat was replaced 5 years ago and have obviously been setup and working correctly.
With power turned on, and the thermostat set up for heating mode, I have indication of power on both BLACK hot lines at the heater. Even when thermostat is switched OFF, I have indication of power at the heater.
Is it something wrong with the thermostat?
