How to Replace 3204267 High Limit Thermostat on Frigidaire Dryer — Step-by-Step

Your Frigidaire dryer shuts off mid-cycle with an E65 code flashing on the display. Or maybe it runs fine but blows nothing but cold air. One frustrated owner said their "heater had fried" before they "replaced it" — and that's exactly what happens when the 3204267 high limit thermostat trips repeatedly due to restricted airflow. This safety device is designed to shut everything down when temperatures get dangerously high, usually because your vent tube is packed with lint.

The good news? This is one of the easier dryer repairs you can tackle yourself. The thermostat is a small disc mounted on the heating assembly, and with basic tools you can swap it out in under two hours. Let's walk through exactly how to do it.

What You Need Before Starting

Gather these tools before you begin:

• Phillips and flathead screwdrivers
• Needle-nose pliers
• Work gloves (metal edges can be sharp)
• Flashlight or headlamp
• Vacuum with hose attachment

Repair time: 1-2 hours | Difficulty: Easy

This repair works for Frigidaire, Kenmore, Electrolux, and Gibson dryers including models FFLE2022MW2, FFLE3900UW1, CAQE7021LW0, CFLE1011MW0, and Kenmore 110-series dryers. The 3204267 thermostat replaces AP2131477, 508516, PS446428, and AH446428.

Safety First

Unplug the dryer completely before starting any repair work. For gas dryers, turn off the gas supply valve as well. The heating element and surrounding components may have sharp edges, so work gloves aren't just optional — they'll save your knuckles. Make sure the dryer has been off long enough for all components to cool down completely.

Step 1: Access the Heating Assembly

Pull the dryer away from the wall so you can work comfortably. Most Frigidaire dryers have the heating element accessible from the rear panel. Remove the screws holding the back panel in place — there are typically 6-8 screws around the perimeter. Set the panel aside carefully. You'll see the large cylindrical heating element assembly, usually on the right side. The high limit thermostat is a small circular disc (about the size of a quarter) mounted directly on the heating element housing with two wire connectors attached.

Step 2: Disconnect and Remove the Failed Thermostat

Take a photo of the wire connections before you disconnect anything — this'll save you headaches during reassembly. Use your pliers to gently pull off both wire connectors from the thermostat terminals. They're push-on connectors, so they should slide off with steady pressure. Don't yank them by the wires themselves. Remove the mounting screw holding the thermostat to the heating element housing. The old thermostat should lift right off.

Step 3: Clean the Vent System (Critical Step)

Here's what most people skip — and why they end up replacing this part again in six months. The E65 error code appears because your dryer overheated due to restricted airflow. That restriction is still there even with a new thermostat installed. Disconnect the vent tube from the back of the dryer and use your vacuum to clean it thoroughly. Check the exterior vent hood outside your house too. If your vent run has multiple bends or is longer than 15 feet, you might need professional vent cleaning to get all the lint out.

Step 4: Install the New 3204267 Thermostat

Position the new thermostat exactly where the old one sat on the heating element housing. The metal disc should sit flush against the housing for proper temperature sensing. Thread in the mounting screw and tighten it firmly, but don't overtighten — you can crack the ceramic insulation on the thermostat. Push the two wire connectors back onto the terminals. They should click into place and feel snug. Give each wire a gentle tug to confirm they're fully seated.

Step 5: Reassemble and Test

Reattach the rear panel and secure all screws. Reconnect your vent tube, making sure there are no kinks or restrictions. Push the dryer back into position, plug it in (and turn the gas back on if applicable), and run a test cycle. The dryer should heat normally without triggering any error codes. Let it run for at least 20 minutes to ensure the thermostat doesn't trip prematurely.

Testing After Installation

Start with a timed dry cycle on high heat with a few damp towels inside. The dryer should heat up within the first 5 minutes. Feel the exhaust air coming out of your exterior vent — it should be warm and flowing freely. If you still get cold air or the E65 code returns, you've got a deeper airflow restriction problem or possibly a failed heating element that needs addressing. The thermostat itself is working fine if you installed it correctly.

Frequently Asked Questions

How can I test the thermostat with a multimeter?

Set your multimeter to the lowest ohms setting. Touch the probes to both thermostat terminals. At room temperature, you should get a reading of near zero ohms (continuity). If the thermostat has tripped, you'll get an infinite reading (no continuity). However, if you're getting an E65 code and cold air, don't just test the thermostat — clean your entire vent system first, because that's what caused the thermostat to trip in the first place.

Will this fix my dryer if it's blowing cold air?

Cold air from the dryer means either the high limit thermostat has tripped (shutting off the heating element as a safety measure), or the heating element itself has failed. If you're getting an E65 error code along with the cold air, the thermostat is your culprit. But remember — the thermostat tripped for a reason, usually lint buildup restricting airflow. Replace the part AND clean your vents, or you'll be back here in a few months.

How often should I replace the high limit thermostat?

You shouldn't need to replace it at all if your dryer vents are clean and airflow is unrestricted. The high limit thermostat is designed to last the life of the dryer under normal conditions. If you're replacing this part repeatedly, you have a chronic airflow restriction problem — likely a clogged vent tube with too many bends, or a blocked exterior vent hood. Fix the root cause or you'll keep burning through thermostats.
