Frigidaire Dryer Switch Replacement: Door Switch

Both switches are cheap mechanical parts, and telling them apart is quick.

Door switch#

Mounted on the front-panel frame by the door opening, the door switch is pressed by a small striker on the door as it closes. On Frigidaire dryers it's a separate part from the door catch — unlike some machines where the latch and switch are combined.

The reversal trap: every Frigidaire dryer door can be hung on either side, and there are pre-drilled switch mounting holes on both sides of the front panel. If someone reversed the door but left the switch where it was, the striker no longer lines up with the plunger and the dryer won't start — a common gotcha on second-hand units.

Door-switch symptoms:

• The dryer does nothing at all — no motor, no heat, no tumble.
• It starts, then stops instantly as though the door opened.
• It runs with the door open — the switch is stuck closed, which is a safety hazard; replace it immediately.

Test it on continuity: pressed plunger reads continuity, released reads open. No change means a failed switch.

Start switch#

The push-to-start button on the console is a momentary switch — press it, the motor starts, the cycle runs. It sits behind the console with the other controls. It's failing when a press does nothing at all (no click, no motor) while the door switch and other controls work, or when it takes several jabs to catch. Test for a momentary continuity blip while the button is held.

Replacing the door switch#

1. Unplug the dryer.
2. Open the door; the switch is on the front-panel frame — a small rectangular body with a plunger, held by 1–2 screws.
3. Disconnect its wires (2 or 3 depending on model).
4. Remove the screws and pull the switch.
5. Fit the new one in the same spot, reconnect, and make sure the plunger lines up with the door striker.
6. Close the door and start a cycle to confirm it runs, then open the door to confirm it stops.

Tools: Phillips #2, multimeter — about 10–15 minutes.

Replacing the start switch#

1. Unplug the dryer.
2. Pry off the console end caps with a flat-blade screwdriver.
3. Remove the console screws at each end and tilt the console forward.
4. Find the start switch behind the Start button.
5. Disconnect its wires and release the clip or screw.
6. Fit the new switch, reconnect, and check the button clicks positively.
7. Reassemble the console.

Tools: flat-blade screwdriver, Phillips #2 — about 15–20 minutes.

Parts and cost#

Check alignment after a door reversal#

If the dryer was recently reversed — or you inherited it and aren't sure — verify the door switch first: close the door, note where the striker meets the front panel, and confirm the switch plunger sits directly behind that point. If it's on the wrong side, move it to the matching pre-drilled holes. It's the fastest thing to rule out before buying any part, and it costs nothing to fix.

These are simple, long-lived switches — the door switch and start button usually give many years before their contacts wear — so an early failure is worth a second look for a mechanical cause like a bent striker or a door that no longer seats squarely against the panel.
