Doesn't heat anything


It sounds like the micro generator has died.

Yes, you should buy a new one as the cost of repair is likely to be high.

Not heating


If the oven is doing everything else properly (light comes on, fan runs, turntable goes around) but there's no heat, you may have a failed magnetron tube (the microwave source). There's also a relay that controls power to the tube that may not be working correctly, or the control circuit board is bad. It's also possible one of the door switches is not working (so the oven thinks the door isn't closed), although this usually keeps the turntable and fan from running.

Microwave oven service is not for do-it-yourselfers. There are potentially deadly voltages present even with power off, and a chance of microwave leakage if repairs aren't done properly. Let a professional give an estimate to repair it, or just replace it if it's under $100. (When I was servicing these things it wasn't unusual for a repair to cost over half the price of a new one. That's one of the reasons so few shops still work on small appliances.)

Light, turntable and fan don't work


Possibly the light bulb has blown, which has blown on a track on the board which has taken out the turntable motor and the fan. Also, there could be a problem with the door switch.

Sharp 1870 just quit cooking and no turntable


The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil

Dacor dcm24s.light, fan, and control panel work but turntable and heat do not


Most likely the bottom door switch. Dacor units are built by Sharp and that switch is a very common problem. You'd either need to check the switch with an ohm meter or remove the cover of the switch to see if it's burned inside.
