How many little fuses do you have to blow before you figure out that you should find another way to trouble shoot?
I don't get it.
I had to follow up on a guy today, said it was a bad circuit board, the boss had me look at it. Found a pile of fuses on top of the airhandler.
What I do is take out my premade 3 amp circuit breaker and plug it into where the fuse was.
Disconnect and seperate all low voltage wires.
Touch red to green, red to yellow, red to white. Does it work? Yes? Ok theres nothing wrong with the airhandler controls. Or circuit board.
Then start connecting the thermostat and cond unit wires, yes you have to do this live.
Once you connect the shorted wire the breaker trips. Pretty simple.
If it's the cond unit wire disconnect it at the unit and try again.
If it's the thermostat wire disconnect that at the t-stat and try again.
When you find it, follow it down and inspect the wire, or just replace it. Pretty simple.
If it stops tripping when you disconnect the cond unit or t-stat then look there for the problem.
Fuses wasted 0. Tools needed: nut driver, wire cutters, transformer breaker.
