common_failure
Sub PCB relay failures are more common than Main PCB failures in these models. When diagnostic tests point to multiple heating problems simultaneously (broil, bake, and convection all weak), focus on Sub PCB relays before assuming Main PCB failure.
maintenance
The terminal blocks on this model corrode frequently in high-moisture kitchen environments. Preventative inspections every 2 years and cleaning corroded terminals with a wire brush can extend the appliance lifespan by years.
repair_tip
If a customer reports that the oven preheats but temperature drops when food is added, the bake element is likely failing or the sensor connection is loose. It's not user error - verify heating element resistance and sensor connector firmly.
