4. Setup and Installation

Installation of the Blodgett 20355 Transformer should only be performed by a qualified service technician.

1. Preparation: Ensure the appliance is completely disconnected from its power source. Access the transformer compartment within the oven.
2. Removal of Old Transformer: Carefully disconnect all wiring from the existing transformer, noting the position and color of each wire. Remove the mounting screws securing the old transformer.
3. Installation of New Transformer: Position the new Blodgett 20355 transformer in the designated location. Secure it using the provided screws or the original mounting hardware.
4. Wiring Connections: Connect the wires to the new transformer according to the appliance's wiring diagram. Ensure all connections are secure and properly insulated.
5. Verification: Double-check all connections for correctness and security. Ensure no wires are pinched or exposed.
6. Power Restoration: Once installation is complete and verified, restore power to the appliance.
7. Testing: Test the appliance's functionality to ensure the transformer is operating correctly and providing the necessary voltage to the control circuits.

5. Operating Instructions

The Blodgett 20355 Transformer operates automatically as part of the oven's electrical system. Once correctly installed and power is supplied to the appliance, the transformer will convert the incoming 115V AC power to 24V AC, which is then used to power the oven's control board, relays, and other low-voltage components. There are no user-adjustable settings on the transformer itself.

6. Maintenance

The Blodgett 20355 Transformer is designed for long-term reliability and typically requires minimal maintenance. However, periodic inspection by a qualified technician is recommended as part of routine appliance servicing.

• Visual Inspection: During routine maintenance, visually inspect the transformer for any signs of overheating (discoloration), loose connections, or physical damage.
• Connection Integrity: Ensure all electrical connections to the transformer remain tight and free from corrosion.
• Environmental Factors: Ensure the area around the transformer is free from excessive dust, moisture, or debris that could impede cooling or cause electrical issues.

7. Troubleshooting

If the appliance is experiencing power-related issues, the transformer may be a contributing factor. Troubleshooting should only be performed by a qualified technician.

• No Power to Controls: If the oven's control panel or low-voltage components are not receiving power, check the input voltage to the transformer (115V) and the output voltage (24V) using a multimeter.
• Overheating: An overheating transformer can indicate an internal fault or an excessive load. Disconnect power immediately and investigate the cause.
• Blown Fuses/Tripped Breakers: Repeatedly blown fuses or tripped breakers associated with the oven's control circuit may indicate a short circuit within the transformer or connected components.

If the transformer is determined to be faulty, it must be replaced with a genuine Blodgett 20355 part.
