Question about Panasonic NN-P794SF Microwave Oven
MANUFACTURED JULY 1995
When you say "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 (the control electronics and light are usually a separate circuit), it's usually a defective/dead magnetron. Given the age of the oven (13+years), this is also points toward the magnetron. The fan _may_ or may not be on the same circuit as the magnetron, that's hard to say without a wiring diagram or schematic.
Prices for replacement/repair will vary, you will need to find out what that service costs in your area before having enough information to decide on repair or replacement. If you tell the repairer that you suspect the magnetron, they should be able to quote you a fairly accurate estimate.
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 ones may have more power/less energy wastage, etc.
