Goodman ARUF..

groundhog

Hi,
This is my first post.

I have a goodman aruf air handler.
Inside there is a control board that has a 3A fuse that was blown. Nothing was working. No fan, no heat from the heat pump. No activity. Only the digital honeywell thermostat was working.

That's when I popped off the lid and saw the blown fuse.
Replaced the fuse. Tried fan only on. This worked.
Then I put the heat to on and set the thermostat 1 degree above room temp. Clickity clack inside the thermostat.... nothing.

Went downstairs. Fuse blown again.

Any ideas?

look for a short .. Mabe outside where the small wires go to the condenser .. Mabe hit with weedeater, dogs , mice etc, will chew on the wires

If it splattered the fuse element all over the inside of the glass sleeve, it was a pretty high current overload. A small gap in the element is a marginal overload.
