Multimeter testing of bake, broil, and hidden elements to measure true ohms resistance against OEM specs, identifying thinning coils before complete element failure.

Digital probe thermal verification across multiple heat cycles to calibrate temperature sensors, correct drift, and ensure accurate baking temperatures.

Micro-gap and compression seal inspection around all perimeter gaskets to prevent heat bleed, excessive kitchen warmth, and unnecessary electrical draw.

Motor bearing spin testing, blower balance verification, and blade clearance checks to eliminate uneven browning, rattling vibrations, and air recirculation delays.

Amperage draw check on glow-bar igniters and solenoid safety cut-offs to guarantee rapid ignition, proper fuel-air mixture, and zero unburned gas release.

Inspection of high-temperature insulated harnesses, terminal block connections, grounding studs, and control board traces for signs of arcing, heat fatigue, or corrosion.
