Kenmore Dryer Won't Start — Door Switch Replacement in Highlands, Denver
We were recently called to a home in Denver's Highlands neighborhood after the homeowner's Kenmore dryer stopped starting entirely. The control knob turned normally and the dryer appeared to have power, but pressing the start button produced no response — the drum would not spin and no heat was produced.
After a complete no-start diagnosis, our technician identified a physically broken door switch as the root cause. We sourced a genuine OEM Whirlpool replacement (Part #WP3406107) from a local Denver parts supplier the same day and had the dryer running again before the end of the visit.

What Causes a Dryer to Not Start?
A dryer that won't start — even when it appears to have power and the controls respond — can be caused by several different components. Before replacing any parts, our technician performed a complete diagnosis to confirm the exact root cause. Common no-start causes on Kenmore and Whirlpool dryers include:
- Broken or failed door switch — dryer cannot detect the door is closed.
- Blown thermal fuse — a one-time safety device that cuts power if the dryer overheats.
- Failed start switch — the push-button switch that initiates the cycle.
- Broken belt switch — triggered when the drive belt breaks.
- Power supply issue — a dryer requires 240V; a partial power loss can prevent starting.
- Failed drive motor — motor won't run despite receiving power.
- Failed timer or control board — cycle control components not sending start signal.
Accurate diagnosis is essential. Replacing a thermal fuse on a dryer with a broken door switch — or vice versa — wastes time and money. Our technician tested each component systematically before identifying the door switch as the failed part.
Step 1 — Complete No-Start Diagnosis
Our technician began by confirming the dryer was receiving a proper 240-volt supply at the terminal block — power was confirmed. Next, we tested the thermal fuse with a multimeter — it was intact and passing continuity. The belt switch and start switch were also tested and confirmed functional.
With all other components testing good, we inspected the door switch — and found it had physically broken. The switch body had cracked, leaving the safety circuit permanently open. Because the dryer's control board could not detect a closed door, it would not allow the motor to start under any circumstances.
Step 2 — Broken Door Switch Removed & Replaced
The broken door switch was removed from the door frame and replaced with a genuine OEM Whirlpool door switch (Part #WP3406107), sourced from a local Denver parts supplier the same day. The OEM part ensures a proper fit and reliable long-term performance — an exact match for the Kenmore 110.68532700, which is manufactured by Whirlpool.
Step 3 — OEM Whirlpool Part #WP3406107
We use genuine OEM replacement parts whenever possible. The Whirlpool Factory Certified door switch (Part #WP3406107) is the correct replacement for this Kenmore model and is designed to meet the original manufacturer's specifications for fit, function, and durability. Using the correct OEM part avoids the reliability issues that can come with aftermarket substitutes on safety-critical components like door switches.

Don't Replace Your Dryer — Get It Diagnosed First
A dryer that won't start is one of the most common reasons homeowners assume their appliance needs to be replaced. In many cases — including this one — the cause is a single inexpensive component like a door switch, thermal fuse, or start switch that can be replaced quickly and affordably.
If your Kenmore or Whirlpool-built dryer won't start, don't assume the appliance is beyond repair. A proper diagnosis is the first step — and it often reveals a straightforward fix that gets your dryer back in service the same day.
