If your AC unit was running correctly before the thermostat failed, then it will be OK to run it continuously until the AM when you plan to shut it off. Just don't freeze tonight because it won't be cycling on and off. When weather is extremely hot, AC units can run continuously and many do down here in South Florida. Just replace the thermostat as soon as ...

This was caused by a defective igniter. These are $150 as OEM replacement, but I used a generic $40 replacement that works just fine. You just have to match the amperage! The oven works as follows: Once you start the oven (mode switch and thermostat) a current will flow through the igniter, causing it to glow yellow/white. The (dual) gas valve is connected ...

I changed the "bad" thermostat for a new good ...

The only thing that could be happening in this case is a broken wire, or a bad splice. A solid, continuous wire will have voltage on the other end, even if its partially damaged. A damaged wire will not have the current carrying capacity (amps) that a good wire does, but it will show voltage. Also, since this is alternating current, the 2 volts you're ...

Imagine you had a working thermostat and you flipped it to "A/C" and set the temperature to 50F. The thermostat would "call for cooling" so long as the temperature is above 50F. Since I bet your system would never get there, that means it would "call for cooling" continuously. That is fine. If your heat pump unit can't run ...

Trane is silly Trane is sometimes silly and calls their C wires B, which is mildly confusing because other brands sometimes use the B designation for the function that your O wire performs, namely heat-pump reversing control. Anyway, you have a perfectly good C wire in disguise as your B wire, so just use that.
