Light stays on in De Dietrich oven DOD438 all the time. It is in the lower oven. Stays on whether door is open or closed. Oven is new since May 2007

Thank you for your inquiry, Lucie!

From what you have described your Frigidaire oven lock is stuck open and you are receiving error codes "F9" and "DR". The "F9" error code stands for runaway temperature (overheating). This could be an issue with your RTD (Resistance Temperature Detector) or the EOC (Electronic Oven Control). I would recommend performing a reset on your oven and you can do that by disconnecting from your oven for ten minutes. The "DR" code means that the door is not closed or the door latch is not recognizing the door is closed. This could be an issue with your door latch or control panel. If the reset does not help correct your issues I would recommend having a professional technician out to perform a proper diagnosis and repair. Best of luck! -Matt

There should be a switch in the door that is pressed in when you close the door. Check the switch by pressing it yourself. If it still doesn't work, replace the switch.

Some have a magnet that operates the switch.

u may have a bad switch.. if the light stays on while all burners are off.. u will have to check each switch one by one to get the right one..

Hi,

Here is a tip that I wrote about why the hot surface indicator light will not go out...

The oven door lock needs approximately 1 hour to cool down before the oven door can be opened after a self cleaning cycle has finished. If the lock does not open after the oven has cooled down, you can try....1) Unplugging the range or shut off the circuit breaker for 5 minutes. Plug the range back in or turn on the circuit breaker. Set the clock and try moving the door lock lever or opening the door. 2) Set the self-clean cycle again and only allow it to work for 15 minutes. Cancel the self-clean cycle and allow the oven to cool. Gently try moving the door lock lever or opening the door.

Most ranges today use 3 different types of door locks...one is a solenoid controlled lock ( you hear a loud buzz noise when setting or unlocking the lock and has a arm that you must move to set the lock )...another is a heat sensitive lock ( has a arm that you must move to lock and un-lock, makes no noises and has a spring that slowly moves to lock the door will the oven is heating up )...Some locks are motorized ( no handle to move, the motor locks the door by it's self when you set the range for self clean )... If the motorized and heat sensitive locks fails to open after the self clean cycle, you must access the lock and move it yourself to open the door. On the free standing ranges, most times you must lift the cook top to access the lock mechanism. On built in ovens, the oven must be pulled out to remove the top access panel to get at the lock mechanism. Some build in ovens can have the control console removed to access the lock system. On the heat sensitive style of lock, there are no electrical parts to operate the lock, usually you will need to replace the lock. On the motorized style of lock, you will have to use a ohm/volt meter to test why the motor will not work. On the solenoid style of lock, the solenoid is often mounted on the back of the range and can be accessed by removing the rear panel, some may be mounted at the front, such as in a built in oven. The failure of the solenoid style of lock is normally caused by a bad lock solenoid. In order to get your door open, you must operate the door latch mechanism manually. Unplug or remove power from the range. Take the rear cover off the range. Locate the door latch assembly and operate it manually and open your door. Then check continuity of the solenoid. Some of the latch assemblies have micro switches to supply power also. You may need to check them. You should be able to get the door open and use your range until you can get a tech to repair if you can not repair yourself.

If you've interrupted the clean cycle or have accidentally set the clean cycle with the oven door open, the latch may have engaged and now the door can't be closed because it will hit the latch. There may be a door activated* switch on the front face of the oven. In this case you may need to manually press that door switch with your finger while at the same time canceling the clean cycle to get the latch to retract so the door can close fully again.
thanks.

great fix

hi,

it sounds like the oven safety valve is bad, it will reach a point when the pilot will make enough energy to keep itself lit, but not enough to open the gas valve to light. it will need to be replaced. if you are handy you can do this, but make sure you shut off the gas to the range first. you should be able to find a replacement online, if not check with a local LP gas company that sells parts to the public.
