Hi, not sure what's going on, I had a 100W ceramic heater connected to pulse-proportional stat to raise the ambient temp.


But it started to just not stay on making the temperature drop.


I changed the thermostat, the bulb, the cable, and the power strip, but kept ceramic holder, and it still would turn off randomly.


I tried bending the metal flap in the holder so it would make better contact, but it didn't help.


Now I changed the holder for a new one, and that hasn't helped either.


Getting frustrated now as everything has been changed, and I donno the problem.


I tried cleaning the contact on the ceramic heater, but its not turning on at all now, even if plugged in without thermostat (so I know its not the thermostat).


Thanks for any thoughts.
