Bunn coffee maker warmer plate is too hot, scorching coffee.

Safety: Unplug the brewer and allow the warmer to cool before inspection.

Steps:

• 1. Verify correct parts: If the warmer was recently replaced, confirm the correct Bunn warmer assembly and wattage were installed.
• 2. Inspect thermostat: On models with a warmer thermostat, test its operation. If it never opens as the plate heats, replace it.
• 3. Check wiring: Ensure the warmer is not wired directly to line without control. Correct any miswiring to match the factory schematic.
• 4. Use appropriate carafe: Use the correct Bunn glass or thermal carafe; some aftermarket carafes can transfer heat differently and appear to overheat.
