How can I determine fuse specs for the air handler's circuit board?
Home Improvement Asked by joe trevi on February 5, 2021
where in the furnace does it say if it uses a 3 amp or 5 amp fuse for the circuit board? Or how would I know which is correct

If the thermostat is relatively close a 3 should work. Further away use the 5. If the 3 blows try the 5. If the 5 blows, you have a problem in the furnace.

It's usually indicated on the board itself as a consequence of the manufacturing process
look closely just behind the fuse 3A

It should be documented in the service manual but this is a easier way to confirm. If you can't determine the size, always go with a 3A fuse. The difference between 3A and 5A on a circuit board is very significant. And a short on 3A board using a 5A fuse is very likely to blow a component.

The board ID number is often specified and Googling the numbers on the board often takes you a valuable information source. This image shows a alternate location for the fuse size.
