CFESA (Commercial Food Equipment Service Association) certification is the industry standard for commercial kitchen equipment technicians. Certified technicians have passed rigorous examinations on electrical, refrigeration, and gas systems. When you hire a CFESA-certified tech, you can trust they have the knowledge to properly diagnose and repair commercial kitchen equipment safely and effectively.

Walk-in door gaskets typically last 2-4 years and should be inspected every 6 months. Signs of failing gaskets: visible tears or cracks, frost buildup near the door frame, condensation on the door frame, noticeably warmer temperatures near the door, or the door not staying closed. A failing gasket forces the compressor to work harder, increasing energy costs and reducing equipment life.

Common causes include: faulty igniter or ignition module, failed heating element (electric ovens), thermostat or temperature probe failure, gas valve issues, or clogged burner ports. Start by checking error codes on the control panel if equipped. If the oven lights but doesn't reach temperature, the thermostat or temperature probe is often the culprit. A certified technician can diagnose the root cause quickly.
