“You remember when people used to find the problem and not just put a bandaid on it? That's the Mechanical company, they will find the actual cause of the problem and get you back working quickly! I had a company come out 3 times to fix an issue with my Rational oven with no success. The Mechanical company found the problem and fixed it!”
Matt Peate · Tim Hortons | Director Of Operations

Rational down mid-service? We answer 24/7.

Common Rational problems we fix

If your Rational is doing this, call us.

Tell us what the display says and what the oven is doing. Our technicians diagnose the actual cause — not just the part that failed last.

  • Service or error message on the display

    A service code or error that stops the oven or locks you out of cooking programs.

  • Not heating, or slow to temperature

    Heating elements, gas burners and ignition, contactors, temperature sensors and controls.

  • No steam or wrong humidity

    Steam generator faults, scale build-up, water level sensors, solenoid valves and pumps.

  • Cleaning cycle failing

    iCareSystem and CareControl cycles that stop part-way, error out or leave tabs undissolved.

  • Door, gasket or seal problems

    Steam escaping, worn gaskets, latches, hinges and door contact switches.

  • Water leaks or a backed-up drain

    Water under the oven, blocked drains, supply and filtration problems.

  • Fan noise or uneven cooking

    Convection fan motors, fan wheels and bearings — the usual cause of uneven results.

  • Core probe not reading

    Core temperature probes and connectors that throw cooking programs off.
