there should be some screw holes along the sides installation instructions should have come with the unit but if they did not can get them here http://www.frigidaire.com/support/ResultsPage.asp?strModel=PLEB27T9DC&User=&Search=Search

I found the lower circuit breaker had been tripped. That didn't fix the problem but upon further inspection whoever had worked on the unit years ago had dropped a screwdriver that had lodged between the oven wall and the rear casing and shorted out the lower heating element. I removed the screwdriver and oven works fine now. I don't think that will solve the cmmclow problem but maybee the curcuit breaker is tripped.

I'm sorry but I am not familiar with Dacor ovens, the research I performed indicated that the ERC (clock module) has failed. You could try the oven sensor probe if it is a temperature related issue.
I truly wish I could help you further with your dilemma but am unable to provide any further information except search the web. Good luck....

You probably tripped a safety thermostat in the back of each oven. If you turn off the breaker and find a way to pull the units out you could probably remove the rear panel and reset the thermostat by pushing in a button on the back of the open thermo. Some thermo's aren't resettable though so you'd have to buy a replacement.

HI - I just had the same problem - repairman came and reset the breaker in the oven which "tripped" (even tho I havent used the lower oven in months).  Read posts here on other Dacor ovens which explain how to get to the reset switch to avoid having $150 in repair costs - I have not tried that myself tho but good luck!
