Dryer Not Advancing? Dryer Timer 3373590 – Fix No-Heat & Cycle Failures Fast

If your dryer runs but won't advance through cycles, stops mid-cycle, or produces no heat, the timer is the most common culprit. In Whirlpool and Maytag dryers, the timer controls the entire cycle sequence — when it fails, the dryer may run continuously, stop prematurely, or skip the heat phase entirely. ⚡ Common failure point in Whirlpool-built dryers manufactured 2000–2015. Part 3373590 is the genuine OEM replacement timer that restores full cycle control and normal drying operation immediately.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dryer powers on and drum spins normally
• ✔ Door switch and start switch function correctly
• ✔ Power supply and circuit breaker confirmed OK
• ✔ Thermal fuse and heating element test good
• ✔ ONLY problem is cycle not advancing, no heat, or dryer running continuously
