Berkshire XL

[Tony Ramirez]

I just Purchased a 40D, the front overhead defroster fans keep blowing the fuse when switched on. Any suggestions?

What year is your Berkshire 40D? it could be a faulty fan motor pulling too many amps and tripping the fuse.

Here's a quick, easy way to measure that current.

1. Get a multi-meter that has a 10A (10 amp) scale. Most of them do, even the $7 ones.
2. Plug the black probe into the COM terminal.
3. Plug the red probe into the 10A terminal.
4. Turn it on.
5. Make sure the fan is off.
6. Remove the fuse.
7. Plug the multimeter probes into the fuse socket. The probe tips will fit nicely into the curled part of each fuse socket terminal.
8. Turn the fan on BRIEFLY and read the current from the meter. If you see blinking "1", the current is over 10 amps. Most fans draw less than 10 amps.

Unplug the fan and see if the fuse still blows. If it does then there is a pinched wire. If it doesn’t blow then the fan is bad.

It is a 2019 XL 40D.

I will try and test current draw this weekend, thanks. I didn't see an easy way to "unplug" the fans, haven't unmounted them. If they are drawing too much current, I'll probably need to replace them. Any suggestions on nice looking, quality replacements?
