No heat only and everything else OK, indicates a problem with the HV (high voltage) circuit in the oven.

No heat and everything else working OK, indicates a problem with the HV (high voltage) circuit in the oven.
This could be the R2 relay on the control board, the HV transformer, the HV diode, the HV capacitor, the magnetron or the wiring between these components.
The R2 relay contacts when operated connect the AC power to the HV transformer primary winding. The transformer in conjunction with the HV diode and the HV capacitor generate the necessary voltage for the magnetron which produces the microwaves which heat and cooks the food as they pass through it.
Here's a [link|https://www.repairfaq.org/REPAIR/F_micfaq5.html#MICFAQ_002|link] that describes how to test each of these components in the oven.
Here's a link to a [link|https://www.searspartsdirect.com/model/evo8bcufmx-000582/kenmore-79080339310-microwave-hood-combo-parts|parts supplier] that is ''useful'' as it has the wiring diagram for the oven as well.
If you find a component which is causing the problem, locate it in the parts list to find the ''manufacturer's part number'' listed with the part. Then search online using the ''part number only'' to find suppliers that suit you best.
FYI your oven is a Frigidaire oven made for Kenmore. Just so you're not surprised when the parts show up as Frigidaire parts. As best as I can tell, Kenmore doesn't make appliances but presumably orders them from other makers e.g. LG, Whirlpool, Frigidaire etc and then renames them.
