Parts for Maytag AQU2003TRW04: 03 - Unit Parts

This sealed-system compressor circulates refrigerant to cool your refrigerator, restoring normal cooling performance when the compressor fails. Designed to replace a failing compressor and help bring temperatures back to safe food-storage levels. What it does:

• Compresses and circulates refrigerant through the sealed refrigeration circuit
• Restores cooling when the compressor motor runs properly
• Commonly linked to symptoms like weak or no cooling, loud humming or clattering sounds, or a refrigerator that cycles continuously
• May be the cause if the appliance frequently trips a circuit breaker or shows hard-starting behavior

• Sealed-system work requires certified HVAC/refrigeration service and proper refrigerant handling per local regulations
• Disconnect power before beginning any repair; follow lockout/tagout practices
• Compressor replacement often requires system evacuation, brazing, and recharge — do not attempt unless qualified
• Use the identical replacement part number and follow OEM service instructions to avoid damage

The Start Device Assembly is an OEM part for Whirlpool refrigerators. It is a kit that includes the start relay and overload, both of which are crucial components for the proper operation of the compressor. The start relay is responsible for initiating the compressor's operation by providing an electrical boost to start the motor. 

Causes of a faulty start device kit can include electrical component failure, power surges, or damage due to wear and tear over time.

Symptoms of a bad start device kit may include:

• The compressor not running or cycling on and off frequently
• Inadequate cooling or fluctuations in temperature
• Unusual noises coming from the refrigerator

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 overload protector is a safety device that mounts on the compressor and opens the circuit if overheating or excessive current is detected. Replacing a failed protector can help restore reliable compressor start-up and protect the motor from damage.

• Monitors compressor temperature/current and interrupts power during an overload condition
• Helps prevent compressor overheating and winding damage
• Common symptoms: refrigerator not cooling, compressor won't start, clicking or humming then shutting off, repeated cycling from the rear machine compartment
• Visible heat damage or a burnt odor at the start device area may indicate failure

• Disconnect power before servicing; work in a well-ventilated area
• Access the rear machine compartment; remove the cover to reach the compressor start assembly
• Note wire positions and orientation; the overload fits on the compressor terminal alongside the start device/relay—seat it fully and securely
• Inspect connectors for heat damage and ensure tight, clean terminals before restoring power

Pan-head screw used to secure panels, brackets and trim on Whirlpool appliances. Replacing a damaged or missing screw restores proper fastening to reduce vibration and keep assemblies aligned during operation. What it does:

• Secures panels, brackets and trim pieces to the appliance chassis.
• Stops loose panels from rattling, vibrating or shifting during use.
• Used when the original screw is stripped, corroded or missing.
• OEM replacement that restores the original fastening point.

• Unplug the appliance or shut off power before working on it.
• Use the correct screwdriver or bit to avoid stripping the head.
• Tighten until snug—do not overtighten or force in plastic parts.
• If the original hole or threads are damaged, inspect the surrounding area before reuse.
