Testing the lid switch on a Speed Queen washer with a multimeter checks for continuity, ensuring it signals the lid is closed for safe spinning.
Tools Needed
Multimeter (set to continuity/ohms), screwdriver, putty knife (for console access), towel for spills. Unplug washer first for safety.
Access the Lid Switch
Most Speed Queen top-loaders (e.g., TR7, TR3 series) have the switch at the console hinge right side.
-
Unplug power and shut off water.
-
Insert putty knife into console seams (left/right front) to release clips; lift console back.
-
Locate switch (small white/black plastic with 2-4 wires: often LINE/NEUT, MOTOR/MACHINE).
Testing Steps
-
Disconnect wires (note positions: e.g., black to timer, red/white to motor).
-
Set multimeter to continuity (beep symbol) or lowest ohms (Ω).
-
Touch probes to switch terminals:
-
Lid closed: Continuity (beep/0-1Ω) between motor and machine terminals (or relevant pair).
-
Lid open: No continuity (infinite Ω, no beep).
-
-
Actuate plunger manually if needed—repeat on all pairs if multi-pole.
Next Steps
Good switch? Check fuse or timer. Faulty? Replace kit (KES 2,000–4,000 via Bestcare); reverse access steps. For Nairobi pros, call Machinerepairnairobi.co.ke if unsure. Test empty cycle post-fix.
