Why Is Your Gas Stove Knob Stuck On?

A gas stove knob allows you to control the flow of gas coming from the stove. It is not supposed to be stuck. 

Because it can be dangerous if the knob is stuck in the open or “on” position. Continuously releasing fuel can become a serious danger in that case. 

The knob getting stuck can be due to various reasons. These could be physical jamming, cheap parts, or a problem with the burner gas valve.

Here’s why your has stove knob gets stuck on:

  • Debris accumulation.
  • Grease and grime clogging up the inner workings of the knob.
  • Cheap parts getting stuck.
  • Lack of regular cleaning of the gas stove knob from inside.
  • Rust or corrosion can also cause the knob to get stuck. 
  • If the knob is broken or cannot be fixed, it needs to be replaced with a new one. 
  • The knob can be loose on the valve shaft.
  • The valve shaft can be loose or wobbly.

How To Unstuck a Gas Stove Knob That’s Stuck?

If your gas stove knob is stuck, there are several steps you can take to try to fix it. Here are some ways to unstick a gas stove knob:

Step – 1

Turn off the gas supply to the stove to stay safe. Then open all the windows around the house.

Step – 2

Do not pull the plastic knob off. There should be a metal peg sticking out (the plastic knob fits over it). 

Step – 3

Check for broken parts, dirt, or grime. Also carefully check for wobbly knob. 

Look around where the knob connects to the stove. Sometimes, dirt or food bits can block it. Clean that area gently.

If it’s still stuck, put a tiny bit of cooking oil or a similar lubricant on the part that’s stuck. Try turning the knob again. 

You can also gently tap the knob and wiggle it. This might help it come free. If this does not solve the issue, proceed with the following steps. 

If machine oil is not available, there are other lubricants that can be used to fix a stuck gas stove knob. 

  • Mustard oil: It can be used to lubricate the knob and make it function smoothly. 
  • White lithium grease: This is a heavy-duty lubricant that can be used to lubricate the knob. A small amount can grease the knob and turn it gently to distribute the lubricant.
  • Cooking oil: Any type of cooking oil, such as vegetable oil or olive oil, can be used to lubricate the knob. Apply a small amount of oil to the knob and turn it gently to distribute the lubricant.
  • Petroleum jelly: This is a multi-purpose lubricant. Apply a small amount of petroleum jelly to the knob and turn it gently to distribute the lubricant.

Step – 4

Upon finding of any of the above, call an expert. The main point of a stuck knob is to never try to fix it yourself. This will cause accidents.

Why Is Your Gas Stove Knob Loose After Unstuck?

The gas stove knob loose after being unstuck could be due to the knob being damaged during the unsticking. Sometimes, instead of the knob getting stuck, it breaks.

You can find the model number for your stove to find a replacement knob that fits properly. If you still have your owner’s manual, check it for this information. 

Other places you might find the model number include:

  • Inside the oven door along the frame.
  • Behind the rear control panel.
  • Under the cooktop if it lifts.
  • On an electric stove, under the left front burner.
  • Inside the drawer.

If the knob is not broken, it could be that the knob is not properly seated on the valve stem. Remove and reseat the knob on the valve stem.

Removal of a gas knob must always be done by a professional.
