How to Fix a Broken Oven Knob Shaft


Usually, an oven knob is a small knob that controls the temperature of your oven and other functions. There may be more than one, but usually, there is only one you use often. The knob’s shaft connects to a metal disc located in the center of your oven (called a “thermostat,” usually) and turns it on and off by pressing the thermostat down or up.

How to Fix a Broken Oven Knob Shaft

Unfortunately, knobs tend to break due to regular wear and tear from opening or to close the door of your oven frequently – the constant motion loosens them inside their casing over time until they get so loose they fall off completely. In this article, I will discuss how to fix a broken oven knob shaft. So let us get started.

Why Is the Knob Shaft Broken? 

The knob shaft breaks because of various reasons. Some of them are listed below:

  1. When someone tries to pull off the knob forcefully using all their strength, the knobs break.
  2. The oven door falls suddenly on a hard surface when one is not standing in front of it. This causes the knob to break due to forceful impact. 
  3. If you or someone in your family has arthritis or carpal tunnel syndrome, then you might end up pulling the oven door open with too much force causing the knob shaft to bend and snap inside.
  4. Any long-term wear and tear can cause stress on any metallic object, which may lead to snapping under pressure, even if the pressure is as low as that of human touch.
  5. Negligence from the user’s end, which leads to the wrong usage, also causes severe damage to oven knobs after time. For example, sometimes you tend to forget where your hand should be placed while opening an oven door, which pushes it with too much strength causing breakage.

A Detailed Stepwise Guide on How to Fix a Broken Oven Knob Shaft:

Step 1

Remove the oven door or drawer from its hinges by removing screws from the underside of the door or drawer. Next, remove any screws holding the plastic faceplate onto either side of the door opening where the knobs were attached, as well as those that hold the entire control panel into place inside of the drawer or door frame. When all four plates have been removed, then set them aside somewhere they will not be lost.

Step 2

After removing all parts of the control panel, unplug one wire at a time from where it is attached to the oven’s circuit board until the entire faceplate has been removed. Next, unbolt two or more screws holding another panel in place inside where the knobs were located to obliterate it so you can access the oven knob shafts.

Step 3

Unscrew any screws that are holding either broken oven knob onto its shaft and pull both knobs off of their shafts entirely so you can replace them with new ones; set ready-to-use replacement knobs aside while you work on fixing worn-out shop ones.

Step 4

Clean  Grease  and  Built Up Residence Off Both  Ends Of  Each  Ovenknob

Clean grease and built-up residue off of both ends of each oven knob shaft with a dry cloth or paper towel.

Step 5

Slide new oven knobs over the shafts from where your newly cleaned grease and residue-free ends protrude from before until they click into place; lock them in by tightening screws on new knobs once they are inserted far enough to do so.

Step 6 

Dial both of the replaced knobs down to “0,” then unplug one wire at a time from where it was attached to the circuit board and attach it back again in the same spot. Next, reassemble the control panel and oven door/drawer in the exact reverse order you used when dismantling them. Once everything is back in its place, reattach all screws that were removed during this process. Finally, once all oven components are back in place, reattach the oven door or drawer back to its hinges by screwing them securely into place.

Step 7

Finally, try out your newly fixed knob(s) to be sure that they work correctly by turning each one slowly just far enough so you can hear them engage then turn off. Once you have confirmed that both knobs turn smoothly, return the control panel’s faceplate and oven door/drawer’s plastic plates into their original places, then tighten screws for each one before placing any sellotape or stickers over them as is- do not replace screws if using sellotape.

Precautions While Fixing a Broken Oven Knob Shaft

If you are still under warranty, it’s best to contact the company before attempting the repair. You risk voiding your warranty by tampering with it.

Don’t use any power tools for this project! The tiniest drill bit can break inside the shaft and render your oven completely useless. Also, take special care not to strip out the screw holes when taking off the knob mechanism.

Keep in mind that ovens come in various shapes and sizes depending on the model number, manufacturer, etc., so if you’re unsure about how yours is made or what size parts you’ll need, check your user manual or find another broken one of the same kind to take apart. That way, the assembly will be exact, and there won’t be any guesswork involved.

How Do You Fix an Electric Stove Knob?

When the knob on your oven breaks, you risk accidentally turning the heat up or down when cooking. Fixing it is easy with screwdrivers and needle-nose pliers. This saves money because you don’t have to call a maintenance specialist. Electric stove knobs are inexpensive (some can be found for under $10). They remove from their shaft by slowly pulling them off with your fingers.

Turn the broken knob counterclockwise until it comes loose; then pull it straight up to obliterate it. You can use this same method for any stove knob, including gas stoves (make sure not to turn on an electric stove without a working knob if there’s no circuit breaker). First, you’ll want to clean the shaft on your stovetop. There may be gunk stuck inside. Pull this off with needle-nose pliers, exposing a new knob’s threads for easy replacement.
