Cooktop Transformer

The Transformer is an OEM part for GE gas cooktops. This component is responsible for converting electrical power to the necessary voltage required for the cooktop's ignition system to function correctly.

Replace this transformer if it fails to supply the proper voltage, leading to ignition issues. Common causes of a bad transformer include electrical surges, overheating, or normal wear and tear over time.

Symptoms of a bad Gas Cooktop Transformer include:

• Burners not igniting or taking longer to ignite
• Clicking sound without ignition
• No power to the ignition system
• Flickering or inconsistent burner flames

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

This light transformer (20VA) steps down incoming voltage for the appliance's light circuit. Replace a failing transformer to restore dependable illumination so you can monitor cooking progress and see clearly when cleaning.

• Steps down line voltage to the lower voltage used by the light circuit
• Supports consistent, reliable interior lighting
• A failed transformer can leave the light inoperative even with a good bulb
• Intermittent operation or flickering can indicate a weakening transformer

• Disconnect power at the breaker or unplug the unit before servicing
• Access and mounting location vary by model; note wiring and orientation before removal
• Move wires one at a time to the matching terminals/leads on the new transformer
• Secure the transformer and route wiring away from hot or moving parts; test light operation before reassembly

This replacement transformer converts household line voltage to the correct level for the appliance's control circuits. It restores stable power to the display and relays so the unit can start and run consistently.

• Converts incoming AC power to the proper voltage for electronic controls and relays
• Failure can leave the display blank and controls unresponsive even though power is supplied
• Intermittent resets or loss of functions can indicate a weakening transformer
• Replace if windings test open/shorted or the part shows overheating damage

• Disconnect power at the breaker before servicing; this part connects to line voltage
• Photograph and label wires; transfer connections one at a time to the new part
• Mount securely and route wiring away from sharp edges and hot components
• Restore power and verify the controls power up normally

This transformer provides the low-voltage power supply required by the appliance control system, enabling proper operation of the control board and related low-voltage circuits. Replaces a failed or noisy transformer to restore reliable control power. What it does:

• Steps down mains voltage to the appliance's low-voltage control circuit for the control board and relays
• Helps restore control functions when a failed transformer causes no power, intermittent control operation, or unresponsive electronics
• Prevents control-board brownouts by providing consistent low-voltage feed (when the transformer itself is the issue)
• Used wherever a dedicated appliance control transformer is required by the appliance's electrical system

• One replacement transformer

• Always disconnect power to the appliance before accessing electrical components
• Verify wiring locations and terminal IDs before removing the old transformer; label wires if needed
• Transfer mounting hardware and brackets from the old part unless new hardware is explicitly included

This power transformer assembly converts incoming line voltage to the lower-voltage supply used by the appliance's control electronics. Replacing a failed transformer restores proper power to control boards and related circuits. What it does:

• Converts house voltage to the control circuit voltage used by the appliance
• Supplies stable power to the main control and display electronics
• A faulty transformer can cause power loss to controls, no display, or intermittent operation
• Works as part of the appliance's electrical supply and control system

• Disconnect all power to the appliance before beginning work to avoid shock
• Handle the assembly and its connectors gently; avoid bending pins or wiring
• Verify connector orientation and secure mounting before reapplying power

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
