CTB temperature adjustment knob shaft

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!

The first thing to look for is the temperature probe inside the oven. If it is bent and touching the side of the oven, the oven wall will cool the probe, and the oven will always be to hot.

Then next answers depend on the vintage of the oven.
If the oven always runs 20? hot (for example) it is possible to adjust the set point on older ovens by removing the oven temperature setting knob and by using a long thin screw driver through the centre of the shaft to adjust the oven temperature to match the oven setting. You will need to buy or borrow an oven thermometer.

to change just the knobs they usually just pull off by pulling straight out on the old ones i recomend getting factory replacement vs universal replacement due to the adjustment on the dials may not be acurate

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.

Oven will not hold correct temperature:------- This can be caused if temperature probe not working.Resistance across temperature probe leads at room temperature (70°F) should be approximately 1096 ohms.----------- Other possibility for this problem is :--- Temperature control not calling for heat.When heat is required, there should be continuity between terminals 6 and 7 on temperature control.-----------Inadequate or improper ventilation.Check ventilation hood. Verify draw and make up air adjustment.-----------If all this checked out ok then its calibration problem.For calibration follow this procedure:--
It can be problem with temperature controller. TEMPERATURE CONTROLLER (Standard-Control Models Only) The calibration of the temperature controller should not be changed until sufficient experience with cooking results has definitely proved that the temperature controller is not maintaining proper oven temperatures. Before any recalibration is attempted, the oven temperature should be checked by the following procedure: 1. Remove all trays and pans from the oven. 2. Place a thermocouple or a reliable mercury oven-type thermometer at the center of the middle rack. 3. Turn the oven ON and set the temperature control knob to 400°F. 4. The amber "heat on" light will go out when the oven temperature is reached. 5. Allow three cycles for the temperature to stabilize. 6. Read the thermocouple or thermometer immediately after the light goes out for the third time, and again immediately after it comes on the next time. 7. If the average of these readings varies by more than 10°F from the dial setting, recalibrate by the following procedure. Recalibration should be attempted only by a competent service technician. Use the following procedure to recalibrate the oven: 1. Loosen the two set screws that secure the temperature-control knob to the temperature-control shaft. 2. Remove the knob from the shaft, being careful not to rotate the knob or shaft. 3. Replace the knob on the shaft so that the indicator mark on the knob points directly at the temperature that was measured at the center of the oven. 4. Re-check the oven calibration. ----------- Part number for temperature probe is 1181996 and you can order if from the Southbend service center. -------- If you want the manual and wiring diagram for your oven.Please click the link directly:-- http://www.retrevo.com/search/v2/jsp/mytrevo/myTrevo.jsp?page=man ----------- after you click the link,a page will open in that you fill the 5 letter number.And click the "download now " option.It will ask you to save or discard.Click the save option and download will start.It will take 2 mins to download.Then click the download file to open it.And go through the manual.------------This will help.Thanks.Helpmech.

Hello there
Electronic ovens with a digital display use a sensor to monitor oven temperature. To solve temperature problems for these models, you may need to replace the sensor. On some digital-display models, you can calibrate the temperature using the key pad. See your operator's manual for details. Ovens without a digital display often use a mechanical system for controlling temperature. On many of these units, you can remove the thermostat knob and adjust the knob itself to more accurately represent the actual setting of the thermostat. If, when you remove the knob, there's a screw on the back of it with a small calibration plate, you can loosen the screw, adjust the plate, then tighten the screw again. If the knob isn't adjustable, and the oven temperature is off by more than 30 to 40 degrees, you need to replace the thermostat to solve the problem.

solved by rotate the temperature knob!!!
maybe would be a problem of the potentiometer or knobe of temperature

under the oven knob is the screw that adjusts the temp. remove the knob and with a small blade screwdriver adjust the temp according to your wife's oven thermometer CW+hotter CCW=cooler
then on the back of the knob is a screw to adjust the position of the knob with respect to the marker

First contact GE directly, they will send you replacements for half that price and you can do the labor yourself. 1-877-959-8688

It's on page 32 of the manual for Thermador's built in convection ovens. 1. turn off the oven 2.touch and hold the start pad and then touch the bake pad 3. 0 (zero) appears in the temp digits. release all pads 4. touch bake and 0 changes in increments. max adjustment is 35 degrees F. 5. to complete change touch start for lower oven on double ovens do this: touch the roast pad instead of the bake pad continue with steps 3-5.
