Safety first: Ensure your hands are dry when working with electrical components.

• Check outlet and breaker: Test the outlet with another appliance and reset any tripped breakers or GFCI outlets.
• Inspect power cord: Look for cuts, burns, or loose connections at the plug. Replace the cord if damaged.
• Internal fuse: If accessible, check the internal fuse on the control board or power module. Replace only with the same type and rating.
• Control board power: If the fuse is good but no low-voltage power is present, the power supply section of the main board may have failed and require replacement.
• Professional help: If you are not comfortable working with mains voltage, contact a qualified technician.
