11:40 PM: Discover cold air blowing through the vents. Wow. It’s just one thing after another with these AC/Heating units, isn’t it?
2:06 AM: So far, I’m batting 3 for 3 in fixes with this thing, because tonight, I managed to get it kicking out heat. Had to grab the code from the blinkie blinkie thing, look up the error (it’s a code 4, Roger- no, really, it’s a Code 4.) Code 4 means the open high temperature limit device is bad (usually.) So after searching around a bit, I located it and took the two wires off and connected them together with some fusable link wire. It’s a little sketchy (read: potential fire), so I have to sort of monitor it while the house is heating. Once the house heats up a bit, I’ll shut ‘er down.
Tomorrow I’ll have to buy a l190f-30 Limit Switch. But from where?
8 AM, (the next day): Woke up and kicked the heat on, but no dice. Dang, it was just working when I went to bed 4 hours ago! So I go to inspect and there is no apparent reason that it won’t start. It’s still jumpered, sans limit switch. When I power it on, the burner(?) glows and the gas starts, but only two valves work, then the whole things shuts down, again.
So I take a cloth rag and start to clean down anything that might be blocking the gas from its intended path. Start it up, it works!
11:30 PM: Work has been busy, so the house has been heating and I’ve been watching to make sure nothing crazy happens, since we’re working without a net (limit switch.) I make a few calls, but either that part has to be ordered or I have to travel to SLC. One guy, however, tells me to tap on the limit switch, gently, with a hammer or something. I choose the back end of vice grips, but still nothing works.
A friend, who is also a neighbor offers to help me and buy the part, but he’ll need to see the part. So I take the limit switch out and figure, what the heck- I’ll clean this thing up a bit. But only a bit- I have no idea how sensitive these things are, but once it’s as clean as I dare, I put it back it, start it up…
…we have liftoff. Everything’s working. Probably time to buy a new filter, though.
