Rational Oven PCB Repair in Northbridge Perth | PEMS

A Rational combi oven at Louder Louder, located on Lake Street in Northbridge, stopped turning on during a busy service period. For a commercial kitchen running a full covers schedule, a non-functional oven means halted production, wasted prep, and direct revenue loss.

The Fault

PEMS technician Philip attended site and found the cabinet high limit had tripped, cutting power to the unit. After resetting the limiter, an error 39 code appeared, pointing to a fault in the potentiometer on the Sicotronic control PCB responsible for temperature setting. Philip checked all connections and ran the oven, confirming the PCB was compromised and would require replacement if the fault returned.

The Repair

Philip returned to site the following month and completed the full scope of work. He replaced the faulty Sicotronic control PCB, the chamber high limit safety temperature limiter rated to 365 degrees Celsius, and the filter cartridge for the water system. Once all components were fitted, the unit was set up and tested to confirm correct operation across temperature ranges.

The Outcome

The Rational oven was restored to full working order, giving the Northbridge kitchen a reliable and properly calibrated unit ahead of the summer trading period. Louder Louder could return to full production without further interruption.
