Hi


Thanks for using FixYa. Many things can cause this like a power relay, loose high voltage wire, cold solder joint on a board and/or magnetron. If it’s a loud hum/buzz sound then 90% it’s usually a bad magnetron and other times it’s a bad high voltage diode. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

My Dacor PCOR30 only works 58-59 seconds at a time. I've read this could be a control board issue (part No. 66660). Is this correct? Is there any other possible cause?


Not likely.

This is a problem in one of the damper-related components, either the switch or motor or the damper door may be binding.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Dacor-branded PCOR30-series microwaves are just cosmetically altered versions of the Sharp R1870-series ovens.

These Sharp-made models stop after 59 seconds when there's damper toruble.

See the attached sample drawing below for a typical damper assembly.

We have the applicable service manuals for the Sharp models and have uploaded it to our site here and here to help you in disassembling and troubleshooting your Dacor version.

You can find the Dacor PCOR parts list here and you can order Dacor parts by part number here.

If a switch is all you need, we offer a universal type for only $7.50 postpaid which you can order here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Pcor30s shuts off at 59 sec mark. Do I need to take down to get to damper motor,switch and door? Is it on rt. Side? Thanks, rick


They're on the left side, and yes, you need to remove the oven from the wall, then take off the outer cover to get access.

This Dacor oven is just a cosmetically-altered version of the Sharp R-1870-series ovens.

So the installation instructions for the R-1870-series will help you get it down. They're here.

We have the R-1874 service manuals here and here, and the PCOR30 parts list here.

Microwave wasn't heating properly and now the door won't open. The button you push to open the door usually has tension on it but now it has none.


You can remove the control panel assembly, then you'll be able to see the door opening parts.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

The Dacor PCOR30 is essentially a rebranded Sharp R-1874, so the relevant Sharp service manuals (here and here) will help you with disassembly if you need more help.

The Sharp manuals will not have the proper Dacor part numbers.

For that, see the Dacor PCOR parts list here.

Our favorite place to order Dacor parts is by part number from the Pros here.

The microwave stops after 50-60 seconds regardless of the amount of time left on the panel

The service manuals that cover these models are here:

http://www.microwavedisplay.com/r1870_r1871_sm.pdf
http://www.microwavedisplay.com/r1850_r1851_sm.pdf

The above manuals will not have Sharp part numbers, not the Dacor part numbers, but they should work, and you can order them from
the Sears Parts Directimage-4235112-10659157 site.

But if you're leery or unsure, you can look up the Dacor part numbers in the part list here, then order by part number from the Pros here.

Microwave does not heat. The light goes on, the turntable turns, it makes a sound and beeps when done. It just doesn't heat.
