Carrier 8000 TS - code 24 ?

jumpball

I have a carrier 8000 TS - Installed may 2003
1. furnace won't turn on
2. code 24 ( 2 short and 4 long light flashes)
3. code 24 says : secoundary voltage fuse is open - check for - short circuit in secoundary voltage wiring (24 VAC) wiring
what are my steps to fix this?
Thx
PS: My furnace was working till my hot water tank broke and water was around my furnace . I cleaned it up and used a hair dryer to dry the floor. I thought I was careful to ensure it was not close to the furance. Now the water tank is fixed by furnace won't turn on.

The fuse is located on your circuit board(in the front), It is a 3 amp automotive type fuse. If you dont have a 3amp you can use a 5 amp fuse but not any higher. Try replacing the fuse and if it blows again then you know you have a 24v short somewhere.

Perfect! I replaced the fuse and the furnace is up and running. Thank you for saving me a service call that I have cancelled for monday!

I had the same problem this morning and woke up to a cold house. After reading your posts I checked the circuit board for the fuse and it was not fully plugged into the board. The furnace was up and running five minutes later. Many thanks!

Thank you very much! I shorted the unit out when the maintenance man left a wire unplugged and it sparked. I found the 3 amp fuse and replaced, voila! Thanks a million!!
