Question about Panasonic NN-P794SF Microwave Oven
When you say "putting out no heat", I take that to mean it's not heating the food up. When a microwave suddenly stops heating food, but still appears to run, it's usually a defective/dead magnetron. Prices for replacement/repair will vary, you will need to find out what that service costs in your locality before having enough information to decide on repair or replacement.
When my first microwave lost it's magnetron (~20 yrs ago), it was 5 years old at the time, and the cost of buying a new oven was only a little more than the repair - but I had the repair done anyhow. Since then, we've replaced the entire oven instead (twice). Newer one's may have more power/less energy wastage, etc.
If it's ~ 3 years old, do you have an extended warranty? If so, you might be able to use that (check the terms of the EW). Most standard warranties are for 1-2 years max, so unless you bought the EW, you're probably back to deciding between repair and replacement.
If I can be of further assistance, or if you have questions about any of my response(s), please let me know before rating me.
If this solves the issue, please rate it accordingly. My goal is to earn a "FixYa" rating from everyone I help.

It sounds like a probemI with the inverter.
Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.
I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:
