How to Replace 134844410 Selector Knob on Frigidaire Range — Step-by-Step

Your Frigidaire range knob just spins without changing settings, or worse—it cracked when you tried turning it this morning. That's the selector knob (part 134844410) telling you it's done. This control knob manages your oven's cooking modes, and when it fails, you're stuck without proper temperature control. Good news? This is one of the easiest range repairs you'll ever do.

What You Need Before Starting

This repair requires almost no tools and takes about 5 minutes:

• New 134844410 selector knob
• Work gloves (optional, for grip)
• Flashlight (to see the control shaft clearly)

Repair Time: 5 minutes

Difficulty: ● Easy — Perfect for first-time DIYers

Safety First

Turn off power to your range at the circuit breaker before starting. Even though you're only replacing a knob, it's good practice. Make sure the range is cool to the touch—don't attempt this repair right after cooking. The control panel area can retain heat for 30-45 minutes after use.

Step 1: Remove the Old Selector Knob

Grip the damaged knob firmly and pull straight out from the control panel. Don't twist—just pull. The knob sits on a D-shaped metal shaft and should come off with steady pressure. If it's stuck from years of grease buildup, wiggle it gently side to side while pulling. Some knobs have been on there for 10+ years and need a bit of coaxing.

Step 2: Clean the Control Shaft

With the old knob removed, you'll see the metal control shaft sticking out. Wipe it down with a damp cloth to remove any grease or food residue. Check the shaft shape—it should be D-shaped (flat on one side). If the shaft itself is damaged or rounded off, you've got a bigger problem that needs a control board replacement.

Step 3: Align the New Knob

Look inside the back of your new 134844410 knob. You'll see a D-shaped hole that matches the shaft. The flat side of the hole must align with the flat side of the shaft. Hold the knob up to the shaft and line up the flat edges before pushing. This alignment is critical—if you force it on wrong, you'll crack the new knob immediately.

Step 4: Install and Test

Once aligned, push the knob straight onto the shaft until it sits flush against the control panel. You should feel it snap into place. Give it a test turn through all settings—Off, Bake, Broil, and any other functions your model has. The knob should turn smoothly with distinct clicks at each position. If it feels loose or wobbly, pull it back off and check the alignment again.

Testing After Installation

Turn the power back on at the breaker. Set your oven to 350°F using the new selector knob. It should hold the position without spinning freely. Wait 10 minutes and check if the oven is heating—if the temperature rises normally, your repair is successful. Test each cooking mode (Bake, Broil, etc.) to confirm the knob engages every setting properly.

Frequently Asked Questions

Will this knob fit my specific Frigidaire model?

Part 134844410 fits dozens of Frigidaire, Electrolux, and Westinghouse ranges including CFRE5711KW0, CRER442AS0, CRGR5700AS0, and many others. Check your model number (usually on a plate inside the oven door or on the back panel) against the compatibility list. This knob replaces older part numbers 134034900, AP4339026, and PS2330885.

Why does my selector knob keep breaking?

Most selector knobs crack from overtightening or forcing them when they're misaligned. The plastic can also become brittle after years of heat exposure from the oven below. If you're replacing this knob for the second time in a year, check the control shaft—it might be damaged and causing the knob to sit at an angle, which creates stress cracks.

Can I use the range without the selector knob temporarily?

Technically yes, with pliers on the shaft, but it's not safe or recommended. The knob provides the proper leverage to engage the switch mechanism inside. Using pliers can round off the D-shaped shaft, turning a $47 repair into a $200+ control board replacement. Order the part and wait the couple days—it's worth it.
