Maytag Dryer MDG9420BWW Timer will not advance

The Dryer Gas Valve Coil Kit is an OEM replacement part for Whirlpool dryers, as well as Kenmore and Samsung dryers. It is a set of coils that control the flow of gas fuel to the burner. The gas valve regulates the precise amount of gas needed to properly combust and generate heat for drying clothes. 

Causes of a bad gas valve coil can be wear and tear from regular use, lime or mineral buildup on the coils over time, or physical damage to the coils.

Symptoms of a bad gas valve coil kit include:

• Inconsistent or incomplete drying  
• Slow or intermittent drying
• Burning smell from the gas dryer
• Improper burner ignition or non-ignition

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

The dryer timer controls the sequence and duration of each cycle. When its contacts or motor fail, the dryer may not start, advance, or shut off. Replacing the timer restores accurate cycle control and automatic advance.

• Sequences power through timed contacts to run motor, heat, and related circuits
• Advances the dial and stops the dryer at the OFF position
• Provides cycle timing for selected settings
• Common symptoms of a failing timer: cycle won't advance, won't start on certain settings, runs too long or won't shut off, only one cycle works

• Unplug the dryer before servicing
• Access the control console; label or photograph wire positions
• Move wires to the new timer one at a time, mount the timer, and reinstall the knob/panel
• Test cycle advance and shutoff after reassembly
