Microwave Waste Line Mover Regular Starter Pulley Parts

This high-voltage transformer supplies the elevated voltage needed by the magnetron to produce microwave energy. Replacing a faulty transformer restores heating performance and reduces risk of electrical faults in the oven. What it does:

• Converts line voltage to the high voltage required by the magnetron to generate microwaves.
• Can cause no-heat conditions when failed; replaces a transformer that no longer powers the magnetron.
• Works with the HV capacitor and diode as part of the microwave high-voltage circuit.

• Disconnect power at the house breaker and unplug the appliance before servicing.
• The high-voltage capacitor can hold a dangerous charge—discharge it properly before touching HV components.
• Use insulated tools and avoid contact with transformer terminals; refer to the service manual for wiring and mounting details.

This H.V. transformer supplies the high voltage needed to drive the magnetron in microwave ovens so food heats properly. Replacing a failed transformer restores the high-voltage supply that powers microwave output. What it does:

• Converts incoming low-voltage power to the high-voltage required by the magnetron
• Enables normal heating; a bad transformer can cause no-heat or weak-heat symptoms
• Can produce humming, burning smells, arcing, or tripped fuses when failing
• Works with the high-voltage diode and capacitor as part of the HV circuit

• One H.V. transformer

• Disconnect power and verify the appliance is unplugged before starting
• Discharge the high-voltage capacitor fully to prevent shock; use insulated tools
• Handle the transformer carefully — it is heavy and mounted with screws/brackets

This idler pulley guides and tensions the dryer belt to keep the drum turning smoothly. Replacing a worn pulley restores proper belt alignment and reduces noise for more reliable drying. What it does:

• Maintains belt tension and alignment so the drum rotates evenly
• Reduces squealing or grinding noises caused by worn bearings
• Prevents belt slipping and poor tumbling performance
• Helps avoid premature belt wear or breakage

• Inspect the belt and mounting bracket when replacing the pulley; replace worn components together
• Disconnect power before servicing and follow all safety warnings for your appliance
• Basic hand tools are typically required; follow your model's service manual for disassembly steps

The Transformer is an OEM component specifically designed for GE microwaves. It acts as the essential electrical converter that receives normal household current and steps it up into the precisely controlled high voltage needed to power the magnetron tube. During use, the transformer transmits regulated H.V. output to ignite the magnetron and generate safe microwave energy for cooking.

Causes of a bad transformer include wear from long-term heat cycling strains and potential pinhole leaks developing over many years of service. 

Symptoms of a bad transformer include:

• Magnetron failing to ignite or running intermittently
• Portions of foods not heating thoroughly on lower power levels  
• Electrical buzzing or burning smells detected
• Microwave slowly losing full power ability over time

This OEM GE replacement is compatible with Hotpoint, RCA and select Kenmore microwave models as well.
