| I keep having a problem with the living room section of my radiant ceiling heat. I have always had a problem with the thermos tat letting the heat be on too long, but that's not my main issue. At randon times the heat in the living room won't turn on. All other rooms work great. I replaced the thermostat last year and it still had a problem although not as often it seemed. Today I traded thermos from the bedroom and still have a problem. Thermo from living room worked great in bedroom, so I reinstalled the original back in the living room. At the thermostat there is power across both lugs on all of thermos I checked in the house. When you turn them on it shows no power and I am assuming I would need to groung one side and that this is normal. A little help would be most appreciated. Michael |

| is there any aluminum wiring in the system? I've seen a lot of these systems where the wirenuts connecting the grids to the controls are aluminum, and corroded. aside from that, verify the grid has not been damaged by expansion in the material, and shorted out a section. it's been a while since I've worked directly with them, but I do not recall a side being grounded, most I have dealt with are 220v, not 110. and it would not be "grounded" it would be connected to neutral, not ground. you may want to take a pic of the wiring and post it here for us to inspect it. |

| Thanks for writing back. I got up in the middle of the night as it was so hot and of course the living room section had turned on. I was guessing on the power issue. What I was saying was that when I went across the lugs on the back of the thermostat with an idiot light, there was power when the thermo is off, and no power when I turn the thermo on. As far the wiring, I haven't been in the attic and don't even have a concept of what I will see visualy. Could you help me with that? Thanks. Michael |

| Yeah well I learned some things. I didn't know there was just a loop of wires up there and I have a partial open, a term from Telephone Company days, in a sealed environment that doesn't have a repair option, great. So an oil heater for 70 bucks instead of thousands to repair. I bought this house two years ago and the seller knew of this problem. What a low life. Michael |
