Jenn Air Cooktop Knob Replacement Tips

Along with your dishwasher, fridge and freezer, your Jenn-Air cooktop is one of the most critical appliances in your home. 

Think about it… Without your cooktop’s help, how would you cook those meals to feed yourself or your family? 

With that said, it’s essential to know how to properly care for and maintain your cooktop, which includes understanding how to replace certain parts and components like your control knobs. 

Below, we’ll be taking a look at precisely that, as well as a few other common cooktop problems and what to do when they happen.

Diagnosing Jenn Air Cooktop Problems

Your cooktop’s control knobs do get a lot of wear and tear simply because you use them every single time that you use your cooktop. Therefore, it’s not uncommon for these components to wear out and break. 

Fortunately, replacing knobs is both inexpensive and straightforward.

Knob Won’t Turn

Your unit’s control knobs will most often crack, split, or break off from the unit itself. 

Other times, however, the knob might get stuck in either the on or off position. 

If your control knob gets stuck while one or more heating elements are on, you’ll first need to unplug the unit from the wall and allow it to cool down before troubleshooting the issue. 

Once cool, start by taking a careful look at the knob in question for any signs of damage or any obstructions that might be preventing it from turning. 

In some cases, dirt or other debris might be blocking its rotation. If so, merely clean or remove the obstruction, plug the unit back in and then check to see if you’ve resolved the problem. 

On the other hand, if the knob is still stuck, you might be dealing with a broken shaft or a faulty switch.

Problem With the Switch

Whether the knob shaft or the internal switch are broken, you’ll most likely need to replace the entire component.

Knob Turns But Cooktop Doesn’t Work

Sometimes, your control knobs might still turn, but you’ll still have trouble getting the cooktop to produce any heat. 

When this happens, you’re either dealing with a broken control knob that’s not correctly engaging the switch, a faulty heating element or an issue with your gas supply (gas appliances only). 

For starters, remove the knob that doesn’t seem to be working and inspect it for any signs of damage. If you can see that the plastic is either cracked, split or severely worn down, there’s a good chance that replacing the knob will get your cooktop working again. 

But if the knob appears to be intact, the next step is to proceed to troubleshoot either your unit’s heating elements or your gas supply.

Test Heating Element

If you’re having trouble getting your elements to produce any heat, you’ll first need to determine whether it’s a single element that’s not working or if all of them aren’t working. 

If there’s only a single element malfunctioning, you can try replacing it with another element that you already know is functioning. If the swapped component works by doing so, it’s a good indication that you’re merely dealing with a faulty element, which you can easily replace. 

On the other hand, if none of your elements are working, it might be time to contact a professional repair technician to help you identify the source of your problem.

Test The Gas Supply

If you’re having trouble with your gas cooktop, you may be dealing with a weak flow of gas, either due to a dirty burner cap or by an issue with the valve that is controlled by the knob. 

Either way, diagnosing or repairing gas appliances is something that you should never do unless you’re trained and qualified to do so. 

So if you need help with your gas Jenn-Air cooktop, don’t hesitate to reach out to Phoenix Appliance Pros today.

Knob Replacement Tips

When it comes to replacing your cooktop’s knobs, swapping out a broken control knob is relatively easy to do, even without any prior experience. 

You can pull off most knobs from the shaft with a bit of gentle force. In some cases, however, there may also be a small screw holding the knob in place. If so, loosen the screw, replace the broken knob, and then re-tighten the screw. 

With that being said, many times, although you might think you’re dealing with a broken knob, the issue might be a fractured knob shaft or a faulty switch, which are both a bit trickier to diagnose or repair on your own.
