If you're referring to the internal 10 amp fuse in the top of the High Pointe Over the Range RV Convection Microwave # HP94ZR there have been owners who found that the door latch has two switches that wear over time and and end up causing the fuse to blow. Replacing these switches should clear up the issue.

How do I change the door fuses on this unit?

@LindaP Sorry for the wait, I had the High Pointe # HP94ZR pulled from the warehouse and took it apart to get to the fuse and took pictures of each step. The way our system currently works I can't post them down here so they'll be above and I'll just name them with letters. I started by opening the door and then taking out the two screws on top of the unit to release the top trim piece (photo A). This piece has plastic tabs that hold it in place so you'll just need to pull it straight out from the microwave. Next there will be a screw to remove on the top that you can see through the grate to release the control panel (photo B). This was a bit tricky to get to. The screw head had such a small depth that I couldn't get a Phillips head screwdriver into enough at the angle they give you so I ended up having to use a small flathead screwdriver to get into the groove and take it out. I used a magnetic nut driver to get the screw back into place when I reattached this part at the end. With the screw removed you can push the control panel up to pop the plastic tabs that hold it in place out (photo C and D). You can then remove the screws holding the aluminum grate at the top out to gain access to the fuse (photo E). Once you replace the fuse you can then reinstall each component in the reverse order.

@KevinC I have the High Pointe No. EC942K9E that trips my breaker everytime I open the door. You mentioned replacing the door switches. How? Where would one get the parts needed? Right now it doesn't start at all so I'm pretty sure the fuse has blown, too. I don't see the point in replacing the fuse until the switches are replaced/fixed. Any help with this would be appreciated.

@JaymeH You would need to reach out to the manufacturer for replacement switches. I agree with replacing the switches first since at least one of them is likely going to just blow the fuse again as soon as you replace it. The manufacturer should have an instruction manual for replacing the switches. I would also check the outlet to make sure it's providing enough voltage for the microwave to operate.

Our 20 amp 125v fuse blew on our highpoint rv microwave (ec942kiw/ ec942k9e after a transformer on out street blew out abd had to be replaced. We replaced the fuse, microwave lit up but as soon as we tried to use it the fuse blew again.,Is the microwave toast? Or could we possibly have gott The wrong fuse?

@Mindy I would try another fuse seeing as how the microwave came back to life shortly when you replaced the first one but have low expectations. You could also reach out directly to Highpoint for their troubleshooting suggestions. They might have a better idea of what a power surge would take out that is replaceable. If you would like to replace it, the Furrion item # FMCM15SS is the closest comparable option to a Highpoint ec942k9e.
