Cannot turn the oven on

Hi Tony! If your Parmco oven temperature knob is stuck, you can try a few things to fix it. Here are some suggestions:

1. Try applying some lubricant: You can try applying a small amount of WD-40 or silicone lubricant around the base of the knob. This might help loosen it up and make it easier to turn.
2. Use pliers: If the knob is stuck, you can try using pliers to turn it. Wrap a cloth around the knob to protect it from scratches and then use the pliers to gently turn it. Be careful not to apply too much force or you might break the knob.
3. Check for obstructions: Sometimes, the knob can get stuck because something is blocking it from turning. Check to see if anything inside the oven might be preventing the knob from turning.
4. Call a professional: If none of the above solutions work, you might need to call a professional to come and take a look at your oven. They'll be able to diagnose the problem and fix it for you.

I hope these suggestions help you fix your Parmco oven temperature knob!

Most likely a control board issue

Sounds like that nob is bad.can u get to see the nob wires to see what's up there?

Pull the knob off of the spindle for the oven control. The temperature adjustment is done by turning the screw inbedded in the end of the spindle. Use a 5/64" blade screwdriver CCW to increase the oven temperature or CW to decrease. Make small adjustments until the dial setting matches the oven temperature.

Hi,

At the bottom of this is a link to the manual, it shows details starting on page 22 of how to clean.

Remove the racks and pans from the oven.

1. Move the Lock Lever to the right-the Clean position.
When the oven temperature goes above normal baking/roasting temperatures, the door cannot be opened and the Lock Lever must not be moved.

2. Set the Oven Selector and Oven Temperature Control Knob to
CLEAN.

3. Make sure the clock and Start and Stop Times all have the correct time of day.
4. Push in and turn the Stop Time Knob clockwise two or three
hours. The OVEN HEATING Indicator Light will come on. l Use two hours for light soil. l Use three hours or more for moderate to heavy soil.
NOTE: Make sure the Start Time Knob is not pushed in.

5. After the Self-Cleaning cycle is completed and the oven has
cooled enough, the Lock Lever can be moved back to the left.
DO NOT FORCE the Lock Lever. Wait until it moves easily. Turn the Oven Selector and Oven Temperature Control Knob to OFF.

6. After the oven is cool, wipe off any residue or ash with a damp cloth.
If needed, touch up spots with a soapy steel-wool pad.


Manual

Use a 'oven thermometer' in the oven and determine the 'actual temperature' in the oven. Your knob setting is off (not calibrated) and the oven is hotter than the control knob setting.

set both start & stop timers to the same time.Turn on the selector and the temperature knobs to clean. Hold in the light button, on the right top side of oven, and hold for 15 seconds.
then turn off the selector knob. hold button again for 15 seconds and the lock should unlock,
then turn off the temperature knob.

After the lock indicator light goes out, move the door lock lever to the left. The oven door can now be opened. Turn the selector and temperature knobs from clean to off AFTER THE DOOR IS UNLOCKED. If the temperature knob is turned to off BEFORE the door is unlocked, the door will not open. Forcing the lock will damage the lock mechanism. If this should happen, return the temperature knob back to CLEAN, unlock the door, THEN turn the temperature knob off.
