Maytag Dryer LDG7400AAL Doesn't shut off

This Dryer Cycling Thermostat is an OEM replacement part for Whirlpool dryers. It monitors internal temperatures and cycles power to the heating element accordingly. The thermostat ensures the drying air reaches and maintains the optimal heat level selected for fast, effective drying results.

Symptoms of a bad cycling thermostat include:

• The dryer not heating or heating inconsistently  
• Frequent trips of the circuit breaker
• Slower than normal drying times
• Burned clothes due to overheating

Causes of failure may be related to normal wear over time, dust buildup affecting sensor readings, or incorrect thermostat calibration. 

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 Door Switch Kit is an OEM part for Whirlpool dryers. This kit includes a door switch that plays a crucial safety and operational role in the dryer's function. It ensures that the dryer operates only when the door is firmly closed, preventing the machine from running with an open door, which could pose safety risks and inefficiency in the drying process.

The causes of door switch failure often include physical damage from slamming the dryer door, wear and tear over time, or electrical issues such as short circuits. 

Symptoms of a faulty Dryer Door Switch include:

• The dryer not starting when the door is closed 
• The dryer continuing to run when the door is opened, which poses a significant safety hazard.
• Unusual noises from the switch area 

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

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.

This thermostat is a temperature-sensitive switch used in the appliance's heating circuit. It opens and closes at a specific temperature to regulate or limit heat, helping maintain correct operation and protect components from damage due to overheating.

• Monitors temperature and switches the heating circuit on/off at its preset trip point
• Helps prevent overheating and heat-related component damage
• Failure symptoms can include no heat or underheating, overheating or burnt odors, or heat that won't shut off
• May cause intermittent heating or frequent cycling as the unit warms and cools

• Disconnect power and allow the appliance to cool completely; shut off gas supply if applicable
• Access the thermostat, note/photograph wire positions, and transfer wires one at a time to the new part
• Mount securely against the proper surface/bracket so the sensor has good contact
• Restore power and test operation; if issues persist, diagnose related heating components per the service manual
