Transformer

The Transformer is an OEM replacement part for GE range hoods. It is an electrical component responsible for regulating voltage levels both internally and to exterior control panels. Proper voltage regulation from the transformer ensures accurate function of hood features like lighting, fan speeds, and exhaust capabilities. 

Causes of a bad transformer typically involve degradation over extended use. Faulty wiring or damage from power surges are other potential causes.

Symptoms of a bad transformer include:

• Lights flickering or not turning on as intended
• Variable or inadequate fan performance  
• Control issues such as buttons not working reliably  
• Abnormal noises from electrical components

This genuine OEM GE part is compatible with GE Monogram and select Kenmore hood brands.

This high-voltage transformer steps line voltage up to power the magnetron, producing microwave energy. Replacing a failed transformer can restore heating when the oven runs but doesn't heat or hums without cooking.

• Supplies the high voltage the magnetron needs to generate microwave energy
• Failure may present as the microwave running but not heating
• May cause a loud hum or buzz with no heat
• Can blow an internal fuse or trip a breaker immediately after pressing Start

• Disconnect power before service; the high-voltage capacitor can retain a dangerous charge even when unplugged
• Support the heavy transformer during removal/installation and reuse original mounting hardware and wire positions
• After installation, verify secure connections in the high-voltage circuit (capacitor and diode) before testing

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 replacement transformer converts household 120V to a 12V control supply to restore low-voltage power for appliance controls and peripherals. It provides a direct, drop-in electrical replacement when the original transformer fails. What it does:

• Steps down mains voltage (120V) to a low-voltage 12V output used by control circuits and relays
• Restores power to control boards, door locks, lights or valves that rely on a 12V feed
• Common symptom: controls or indicator lights are dead while mains power is present
• Common symptom: functions that require the low-voltage supply (locks, dispensers, valves) do not operate

• One transformer (120V primary, 12V secondary)

• Disconnect all power at the breaker or appliance before inspecting or replacing the transformer
• Note wiring locations and secure all connections and strain reliefs
• Mount using existing screw locations or hardware; avoid pinching wires or covering ventilation openings

This replacement transformer supplies the low-voltage power many appliance control boards and user interfaces need to operate. Installing the correct transformer restores stable control-board voltage for reliable keypad and display performance. What it does:

• Converts incoming mains voltage to the lower control voltage required by the appliance control board.
• Helps restore power to digital displays, touchpads, timers and other low-voltage controls.
• Resolves symptoms such as an unlit display, unresponsive controls, or intermittent control behavior when the transformer is the faulty component.
• Designed to match OEM form and function for a direct replacement when the part number and service literature confirm fit.

• One replacement transformer

• Always disconnect power to the appliance before servicing to avoid shock hazard.
• Handle the transformer and wiring carefully; match wire connections and mounting to the original part.

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
