Gas Grill Knobs Hard to Turn [5 Easy Solutions]

The problems discussed in this article are the main culprit behind your hard-to-turn gas grill knobs. Here we will troubleshoot all the problems and come up with their solutions. Let’s start our discussion.

1. Safety Mechanisms

It’s not unusual to discover that the knob won’t turn past the pilot. It is possible that the knob isn’t turning if it’s pressed, or pushed.

Nothing will allow the gas grill knob to run if the unit is too much hot. Consequently, your gas grill won’t light up. You can say this problem is caused by safety mechanisms.


In this circumstance, first, turn the gas grill off. Wait for a few moments until the pilot light goes out.

After that, you will hear a metallic clangor click, as if a spring-loaded mechanism has been disconnected. Then you can easily turn the gas grill on by turning the knob past the pilot without any difficulties.

2. Gas Control Valve Failure

The gas grill knob sometimes does not turn to the right position if the gas control valve doesn’t function properly.

The gas control valve is directly connected to the gas grill knobs. So if the control valve is not perfectly fine, the knobs too will give you a hard time.


It is necessary to replace the gas control valve in order to solve this issue. To replace the gas valve, 

  • Examine the tightness of the valve connection. 
  • With the appropriate size wrench, separate the hex from the gas jets and clean the hole properly.
  • Assess the inner valve portion where the gas jets were removed.
  • Fix the gas jets firmly. Check for leaks with soapy water.

3. A Clogged Shaft

Sometimes, the gas grill knob will just get stuck in the on position and it will not function correctly. A clogged shaft is usually responsible for this. 


Make sure that you remove the gas grill knob before starting the process. Now, using pliers and brute force, turn the shaft until it turns freely again.

This way the clogs that have obstructed the shaft will go be clear. Now, screw the knob clockwise to install it in its position. Now the knob should work just fine.

4. A Hard Gas Grill Knob

Sometimes, your fireplace knob will not turn while the pilot light is still on. However, though the pilot light is on, the gas grill may not work properly. This problem occurs usually due to a stiff gas fireplace knob.


To solve this problem, you need to turn off your gas grill knob. Then, spray some WD-40 into the knob properly. This will loosen up the knob a bit and now you can move it freely.

5. Damaged Plastic Enclosure

The grill knob may appear to be frozen from time to time. The gas grill knob won’t turn on if this is the situation. This issue usually occurs due to a damaged plastic enclosure.


First, remove the plastic enclosure and crank the metal spindle with a wrench to the off position. Then spray it with WD-40. 

Now, turn it back and forth till it moves. After replacing the plastic enclosure, you will be able to turn the knob to the pilot position.


How long do gas grill valves last?

Gas grill valves usually last for 30 to 40 years.

How to turn my gas grill back on?

You can turn your gas grill back on in several ways such as with a key, with a wall switch or remote, and with the control panel.

How to turn on the gas grill knob?

On, Off, and pilot are the three settings on the gas grill’s knob. The gas grill can be turned on by moving the knob to the ON position.

How do I know if my gas valve is bad?

If your gas grill’s gas valve is defective or blocked, it may stop working altogether. This is your signal.

What goes in the bottom of a gas grill?

A drip pan or grease tray is attached to the bottom of the gas grill. This element collects the drippings and grease from the food cooked on the gas grill.
