Understanding the Problem
What the W10186032 is and why it matters: The W10186032 (sometimes listed as WPW10186032) is the mechanical timer/control used on many Whirlpool/Maytag/Kenmore dryers. It sequences the dryer’s cycles and provides switched power to components (motor, heater circuits, etc.) at the correct times. If the timer's heating contacts fail, the dryer may tumble but not heat, or it may not advance through cycles properly. Step-by-step diagnostic checks (in order): 1. Safety first: Unplug the dryer or switch off the breaker before any inspection or testing. 2. Verify the symptom: Confirm the dryer tumbles normally but does not heat. If the dryer doesn't tumble, focus on motor/capacitor/door switch first. 3. Check the thermal fuse: On many models a blown thermal fuse is the most common reason for no-heat. Locate the fuse on the blower housing or near the heating element and test for continuity with a multimeter. Replace if open. 4. Check thermostats and heating element: Inspect the high-limit thermostat, operating thermostat, and the heating element for continuity and visible breaks/shorts. Clean any lint and check the heater terminals. 5. Inspect the timer only after the above are good: With the dryer still unplugged, access the timer wiring and look for burned, pitted, or loose contacts at the timer harness and terminal block. A visible burn or melted plastic indicates timer contacts failed. 6. Test the timer with a multimeter: Refer to the dryer wiring diagram (on the dryer’s console or support sheet). Set the timer to a cycle where heat should be on. Probe the timer’s heater output terminal and the common/line terminal — you should see continuity (or voltage when powered) only when the timer should supply heat. If continuity is missing when it should be closed, the timer is bad. 7. Confirm other controls: If your dryer has an electronic control board in addition to the mechanical timer, confirm the board is supplying power to the timer motor or to the heater circuits as designed. Basic replacement steps (what to expect and how to do it): Tools needed: Phillips and flat-head screwdrivers, nut driver set, needle-nose pliers, multimeter, and a marker or masking tape for labeling wires. 1. Unplug the dryer and move it away from the wall so you can access the back and front. Turn off gas supply if gas dryer. 2. Remove the control console or top panel: On many Whirlpool dryers the console flips up or the top lifts after removing screws at the back. Keep track of screws. 3. Locate the timer: It’s typically mounted in the control panel with multiple spade terminals on the back. 4. Take a picture of the timer wiring or label each wire with tape so you can reinstall exactly as found. 5. Remove the retaining nut or screws and carefully pull the timer out of the bezel. Do not yank wires. 6. Disconnect the wire harness from the old timer. If the harness uses push-on spade connectors, pull straight off; use pliers if needed but avoid damaging wires. 7. Install the new W10186032: Position it so the shaft and mounting holes align, push wires onto the correct terminals matching your labels/photo, and secure the timer with its nut or screws. 8. Reassemble the console/top panel and restore power. 9. Test the dryer: Run a timed cycle and verify the heating element comes on and the dryer advances through cycles normally. Notes on common pitfalls: - Don’t replace the timer if the thermal fuse or heater is open — you’ll waste money and the new timer won’t fix the root cause. - If the new timer makes the same symptom immediately, re-check wiring and confirm voltage is reaching the timer and heater circuits. Safety note: Always disconnect power before working on electrical components. For gas dryers, turn off the gas and check for leaks after reassembly. If you’re not comfortable working with mains voltage, hire a qualified technician.
Common Symptoms
Dryer tumbles but doesn't heat; dryer doesn't advance cycles; intermittent heating correlated with timer position; burned/melted timer terminals.
Common Causes
- Worn or burned timer contacts that fail to close the heater circuit
- Blown thermal fuse or open heating element causing the timer to appear at fault
- Loose or corroded wiring at the timer terminal block creating intermittent/no heat

Helpful Repair Tip
Before replacing the timer, confirm the thermal fuse and heating element have continuity. If both check OK, put the timer in a heating cycle and probe the timer’s heater output terminal — if it never closes, the timer (W10186032) is very likely faulty.
Frequently Asked Questions
Can I replace the W10186032 timer myself?
Yes. Replacing the timer is a straightforward DIY job if you’re comfortable removing the control console and handling wiring. Always unplug the dryer first, label or photograph all wires, and follow the replacement steps above. If you’re unsure working with mains electricity, call a pro.
How do I know if the timer is really bad and not some other part?
Start by testing the thermal fuse, thermostats, and heating element for continuity — they’re the most common culprits. If those components are good and you observe burned terminals on the timer or the timer fails a continuity test at the heater output during a heating cycle, the timer is the likely fault.
