This idler pulley assembly keeps the drive belt properly tensioned and aligned so your appliance runs smoothly and quietly. Replacing a worn or seized idler restores reliable belt drive and helps prevent slippage, noise, and no-drive issues.

• Maintains spring-loaded tension on the drive belt
• Spins freely to reduce friction and belt wear
• Helps route and align the belt between the motor and drum/basket
• Typical symptoms of a failing idler: squealing/chirping, belt fraying or coming off, intermittent or no tumble/spin, burning rubber smell

• Disconnect power; for gas units, also shut off the gas supply.
• Relieve belt tension, swap the assembly, and route the belt per your unit's diagram.
• Rotate the drum/basket by hand to check alignment.
• Wear cut-resistant gloves and use caution around sharp edges and spring tension.

The lid hinge bearing is used for the lid hinges on washers and dryers. When functioning properly, it allows the lid to open and close properly. If this is a problem with the bearing, it could make the lid difficult to move. In some cases, when the lid will not close, it means that the machine will not function correctly. Damaged lid hinge bearings should be replaced as soon as possible.The lid hinge bearings see a lot of work since they are in use whenever the lid of the washer or dryer opens and closes. They could become cracked and broken over time. Replacing the bearings is a relatively simple repair that owners can make on their own.This lid hinge bearing is for use with many models of washers and dryers from Whirlpool, KitchenAid, Roper, Estate, Inglis, Maytag, Admiral, Amana, Crosley, and Magic Chef. This is a genuine OEM replacement part that has been sourced from the manufacturer. The piece is sold individually, so if owners need to replace more than one hinge, they will need to buy multiples.

The Infinite Switch is an OEM part for Whirlpool ranges and cooktops, intricately designed to regulate the heat of the burners. This essential component allows for precise temperature control, enabling users to adjust the heat setting from low to high with infinite variability, hence its name.

Symptoms of a malfunctioning Infinite Switch include:

• The burner not heating up or only reaching a single temperature, regardless of the setting
• The burner heating intermittently or not turning on at all
• Unpredictable temperature fluctuations, making cooking difficult and unreliable

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

If you notice symptoms such as inability to adjust the temperature, uneven heating, or the surface element not turning on or off, it may indicate a faulty infinite switch.

Symptoms of a bad infinite switch include:

• Inability to adjust the temperature
• Uneven heating
• Surface element not turning on or off

Restore your range by replacing the faulty or damaged surface element control infinite switch with this genuine OEM part.
