Commercial Oven Control Board Replacement | SergeComService - Mooresville, NC

Southbend Commercial Oven Repaired in Charlotte – Control Board Replaced, Performance Restored

When a commercial oven begins shutting down during service, the entire kitchen operation suffers. For one busy café in Charlotte, NC, that moment came suddenly when their Southbend convection oven stopped maintaining consistent heat and would reset randomly mid-bake.

Worse yet, two other appliance repair companies had already tried — and failed — to resolve the issue. That’s when the café turned to SergeComService, known across North Carolina for solving what others miss.

The Problem:

The oven’s flame would ignite, then shut down seconds later.

The digital readout flashed erratically.

Sometimes the oven wouldn’t power on at all — until hours later.

Our Diagnostic Approach:

We performed a full diagnostic, tracing the issue to a failing control board that was intermittently losing voltage during ignition. The system logic had degraded, confusing the signals between flame sensor and ignition module.

We also discovered:

Loose ground connections behind the main board

Heat damage on the relay section

A poorly installed replacement sensor from a previous repair attempt

The Fix:

We replaced the entire control board with a new OEM Southbend unit

Repaired and reinforced the internal wiring

Cleaned and recalibrated the flame sensor

Ran a full bake cycle stress test with multiple trays to confirm long-term stability

The Result:

The oven now performs flawlessly. The café’s owner told us,

“We were about to buy a new unit. You saved us thousands. From now on, we’re calling only SergeComService.”
