I have a Trane Heatpump and I'm getting an error 106.00 on

This answer was rated:

HI Pearl; I have a Trane Heatpump and I'm getting an error 106.00 on the thermostat. Nothing will run.
JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?
Customer: Unsure
JA: Do you plan on doing the work yourself?
Customer: only if I'm able.
JA: Anything else we should know to help you best?
Customer: I'm trying to figure out what the code means


My name is ***** ***** I will do my best to assist you. I am looking over your question now and will respond shortly.

This means "an external shut down fault".

Here is copy of the description

This means no power is at or recognized by the air handler. It could be power to unit, bad switch, fuse, breaker, door interlock or board.

It will require checking with a meter to find the missing power

Thank you, Billy! If you were a betting man, where would you think the problem exists? Panel? Fuse?

Most common is at the switch/fuse.

Start at the breaker..make sure 220v avail. Then go to switch..then to next connection. Just follow the wires and test at each stop/connection.

Thanks, ***** ***** Billy. The power was cut off by an "aqua switch" in the secondary drain pipe. The first pipe had gotten clogged , so the pan held some water. Cleared the pipe, solved the problem!

That is great news...really good find.

Just rate service at top of page and I can move off the active list.
