I am planning on updating my about to become outdated smoke detectors. I just can't understand which is better. Also, I am putting one in my full sized basement, the living room/hall/kitchen/bedrooms, and another distant part of the house. Greatly Appreciated! Merry Christmas!
I had a similar problem with my 93 Chevy - thermostat stuck partially open. Easy and cheap DIY fix.
People, pay attention. He verified the gauge is wrong with an IR temp gun. ?, I assume by up to temp you mean 195* or so? That is where it should be running. If it's up to 195*, then yes, you've most likely got an issue with the gauge, wiring, or temp sender, but that's normally not something that works but is inaccuratenormally if they fail, they just stop working. The blend door setups have always been kind of poor on the AC trucks, I would verify that the blend door (for temp) is going from hot to cold. I'd also check if there was a valve from the intake to the heater core, and if there is, I'd make sure its opening and closing fully as it should.
Is this the first time you've turned the heater on in a long time? If so, it could simply be that bits of dust that have accumulated in the system are getting burned off in which case, the problem will solve itself shortly with no problems other than a bad smell for a bit and the noise of the alarms. But it's also possible that the furnace (is it gas or electric?) is actually burning something or perhaps it's exhaust is leaking into the house. That would be bad, and if that's the case you should get it fixed before you use it more. Which is it? I can't tell you. Do you smell smoke? Are you familiar with the smell of a heater that hasn't been turned on in a long time that is now turned on? If so, does it smell like that? If the problem resolves itself relatively quickly, it's probably the accumulated dust burning off that really is the most likely cause. Edit: It doesn't really matter what temperature you set your thermostat at when your heater is on, it's going full blast, and when it's off, it's off. The thermostat just makes it go full blast until your house is as warm as you want it, then turns it off so it's not like your heater gets hotter if the thermostat is higher. Since things seem fine now, I'm guessing that it was just dust being burned out, and you're fine. Being that your heater is electric, that removes the possibility of it's exhaust leaking into the house because there is no exhaust. (If it was a gas heater, the exhaust could very easily be deadly.)
