I have Carrier gas furnaces in the house, one upstairs, one downstairs. Home was built in 1990. They eat thermocouples, which are apparently the devices that keep the pilot light lit. Three have failed in the last few years and low and behold, the upstairs has failed again. By failure, I mean the pilot light won't stay lit. Any explanation or solution to the recurring problem? Looking at the part from previous replacements, looks like a do it yourself job to replace. I've done major automotive work so it doesn't seem too intimidating to me, just awkward to get to.
I've also had to replace the circuit boards a number of times over the years at $300+ per pop and other parts like ignitors and capacitors. Since when are furnaces as reliable as a 1987 Pontiac? Needless to say if I ever have to replace them they won't be Carriers.
