Question about Lasko 5540 Ceramic Compact Heater
Heater keeps shutting off ater short operation.have tried cutting off for ten minutes as suggested in manual instructions, have also checked the timer, but heater runs for a awhile and continues to shut off.
I have a LASKO 5565 model fan and had a similiar problem. Cleaned the whole unit, thinking it was tripping the safety breakers, and it still would turn on and off. The control console was completely unusable. So then I thought that it was maybe the squat switch located on the bottom of the unit. I quickly deduced that not to be the problem and continued following the wiring. Just above the fan there is a 1/2"X1/2" thermostat. Upon touching it I almost burned myself. For some reason the unit was grounding here and cause the thermostat to heat up and shut the unit off. I took the thermostat out of the equation and the unit works great.
CAUTION: If you pursue this action you must understand that you no longer have a thermostat and the unit is now simply just a heater. It will either be on at full blast heat or it will be off. Good luck.

I had one of these that would immediately start to heat up when just plugging into the wall without turning it on! Then it would shutdown from an overheat condition. I found the bad part! Mouser Part #: 771-BT139-800E127
I think the one that was in there was rated 600v, so this 800v is much better. I think this is a hazzard if you ask me. When that part goes out it creates a shorted condition. I put a watt meter on it and it was drawing over 1700 watts. But after replacing the part its been working great since then.
