I have a 2016 CC with the Whirlpool Micro/convection oven. Recently the convection seems like it was not heating up to the set degree. I got a oven thermometer and set the convection to 400, after warming up, and midway thru a 20-minute cook, it only got to 250 degrees. Never did get to 400. Is there any trouble shooting a guy can do? Thanks

If you know how and have an ohmmeter, you can removed the convection heating element and check its continuity. If the meter reads infinity, the element is bad. If the element is good, it's likely an issue with the control board or temp sensor.

OP mentioned that it IS getting up to 250F, which would indicate that the heating element is not "open" or no continuity.. If the element was not heating above ambient air temp then perhaps one could say the heating element is open..

The are a lot reasons as to why it only heats to 250F, sometimes the connections at the heating element fail from not being tight enough after repeated heating cycles. Often push on standard QC connections are used, typically they use off the shelf QC connectors which heat affects the metal enough (300F rated copper/tin) that it loses pressure making a poor electrical connection. The poor connection no longer conducts well enough and the heating element doesn't get full voltage. This often burns up the wire or the element over time if not caught quickly.

Have ran into this with electric smokers..

If one can get access to the element connections, verify that the connectors are not burnt or over heated looking and fit the element tightly.

If the connections are loose or burnt then replacing the QC should fix the issue provided it hasn't damaged the element in the process..

For replacement QCs they make high temperature ones which are nickel plated steel for up to 900F applications.

See HERE

If connections are tight and look good then it could be the temp over heat limit switch has gone bad or the control board..

Typically when it comes to RV microwaves, my first thought is to just replace with a new home MW unit, but dang those combo convection micros are crazy expensive..

You might wish to look up a Whirlpool service center and get a quote to repair.

You can contact Whirlpool Service via Internet HERE They list the average out of warranty Microwave repair as $180-$260 (parts and labor).

Thanks for the info, guys. I did get some local appliance person, he did state (most cases) if you get up to 250, it's probably something else, stating they either work or they don't. The convection like I said is working, I tested it on some brownies, got to 300 and had to cook maybe 5 minutes longer. I also lately have let it warm up a lot more than before I put the food in to bake. I'm in AZ for the winter, they don't make this model anymore, updated it. When I get home, I may pull it and replace it with the replacement one, hopefully the air outlet will be in the same location. They are a little over $500.00. I may reach out to Whirlpool, that would be cheaper. Thanks
