This answer was rated:

Hello I have a Dacor PCOR30S Micro/Convection Oven. Heat Element Cooling Fan starts immediately when plugged in. Oven not working. MicroWave works, but the fan stays on. Service came out and diagnosed a 66660 replacement. That did not work. Any ideas? Out a service charge and possible a control unit. :( Sophia

I am sorry but the phone number you listed above has been blocked by the website. Any personal info will be blocked by the website for security reasons. It just comes up as xxxxxxxxx. We will have to keep all communication to this chat. That is site policy.

However, we can most certainly set up some time if you would like, put a bunch of spaces in between the numbers of your phone number. and we will see if that goes go over a few things. I can show you what to look for and how to check and fix this machine.

Just get back to me here with a day and time that works best for you. And I am in the Eastern Standard Time zone.

Please take a look at the thermostats in the microwave. Specifically the ones that are behind the control panel and the one by the magnetron and blower fan.

With a meter, if you have one, test each thermostat for continuity. If any one doesnt have continuity you will have to replace it. Now you should also check the door switches. I think you had mentioned that you had previously replaced one or all of these before. But I would like for you to check those as well.

Please do this and get back to me here and tell me what you find.

Thank you Jon. I need clarification on where the thermostat actually is. Is it attached to the motor on the outside of the fan (behind the control panel? shaped like a raised quarter?


There are a few thermostats here on this machine so please don't get confused.

If your machine ha two problems, one not heating and two, fan constantly running then you will first have to look at all the door switches again. I would just replace them since they are so cheap. About $20 for all of them. There should be three of them.

And then as far as for the thermostat for the heating element, which in your machine is called the magnetron, is located just on the side of the magnetron. The magnetron looks like this. Click below

The link above is to a video showing you how to remove and replace the magnetron in a similar machine. I know it is not the same model as yours but almost all magnetrons are the same and this video will give you a good idea for what the mag looks like in your machine. And where it is located.

Measure the continuity of that thermostat and the thermostat behind the control panel. And if either one doesn't have continuity then replace them.

The magnetron should it be bad will cost about $100-150 so if that is bad as well you will be into this machine for at least $200-$300 with door switches and magnetron. If this is something you would rather not sink that kind of money into Thenthat is fine. Just get a newer more energy efficient one like a whirlpool or GE. Should be bale to get a good one for about $200-$300.
