Parts for Kenmore 99937CE: Door Switch, Thermostat, Transformer, Relay & Terminal Block Parts

This transformer kit supplies the control circuit with the required low-voltage control power, restoring reliable control operation and cycle control on compatible Speed Queen machines. Designed as a direct replacement for the original transformer assembly. What it does:

• Converts incoming 120V line power to the washer's control voltage so the control board and timers receive stable power
• Replaces a failed or noisy transformer that can cause intermittent control behavior or no power to control functions
• Helps resolve symptoms such as unresponsive controls, no display or cycle start, or erratic control operation
• Matches OEM fit and mounting points for a straightforward replacement when compatible

• Disconnect power to the appliance before starting work to avoid electrical shock
• Follow the manufacturer's service manual for wiring diagrams and correct connector locations
• Verify line voltage is 120V and confirm wiring connections before restoring power
