Common Symptoms & Causes

The following symptoms on your Amana NED4655EW dryer often point directly to a faulty timer that needs replacement.

• The dryer runs continuously and never shuts off at the end of the cycle
• The drum spins but produces no heat during a timed dry cycle
• The timer knob turns freely but the cycle does not advance or progress
• The dryer fails to start at all when the timer is set to any position

These issues are typically caused by worn internal contacts inside the timer assembly, which break down over time due to repeated electrical cycling and normal heat exposure.

• Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
• Take photos with your phone before disconnecting any wiring harnesses or connectors.
• Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

A faulty timer on the Amana NED4655EW will cause the cycle to not advance, stick in one position, or click without changing the cycle phase — confirming the timer motor or internal contacts have failed rather than a control board or user error issue. Identifying these symptoms first ensures you are replacing the correct part and not wasting time on unrelated components.

Step 2

Unplug the dryer from the wall outlet before touching any internal components — capacitors and wiring can hold charge even after power is removed. Remove the two Phillips screws at the rear of the top panel to release the control panel back cover, which exposes the timer assembly sitting directly behind the cycle dial.

Step 3

Set your multimeter to Rx1 and probe across the timer’s motor terminals at each cycle position to test continuity through the internal contacts. An open (no-continuity) reading at a position that should be active confirms the internal contacts are worn or burned and the timer must be replaced rather than repaired.

Step 4

Before disconnecting anything, photograph the wire harness connections from multiple angles — timer wiring is position-specific and incorrect reconnection will cause the wrong cycle functions to activate. Unplug the harness, then remove the two Phillips mounting screws securing the timer bracket, and seat the new timer in the same orientation as the original.

Step 5

Reconnect each harness connector to the exact terminal it occupied on the original timer, using your photographs as a reference — misrouted wires can cause cycles to overlap, skip, or fail to energize the heating element. Reinstall the control panel cover and secure the rear screws snugly but without overtightening, which can crack the plastic housing.

Step 6

Align the flat of the new timer shaft’s D-shape with the matching flat bore inside the knob before pressing it on — forcing a misaligned knob will strip the shaft and require another timer replacement. Plug the dryer back in and manually step through every cycle position to verify the contacts advance correctly and the drum motor and heat engage as expected.

When to Call a Professional

If the issue persists after completing all steps above, the problem may involve the sealed refrigerant system, a failed main control board, or wiring that requires specialized diagnostic equipment. Contact a licensed appliance technician — attempting sealed-system repairs without EPA 608 certification is illegal and unsafe.

Frequently Asked Questions

How do I know if the timer is actually the problem on my Amana NED4655EW?
