Servicing & Contracts

All the information you need on our Rational oven full-service contracts

Why you should have your Rational oven serviced

  1. Regular servicing of your Rational oven can prevent printed circuit board (PCB) damage, as well as identifying any failing or damaged parts which may affect cooking results
  2. Your Rational oven has an air filter which filters cooling air for your oven control panel. This filter can become blocked which can cause components to fail prematurely.
  3. Damaged doors seals and a lack of regular cleaning can also cause component failure as well as affecting cooking results.
  4. Rational periodically release updated software which fixes bugs and improves the cooking specifications and programmes of your oven, especially on older models.
  5. Your Rational oven should be serviced at least once a year to keep it in peak working condition – even if it’s still within its 2-year warranty.
  6. Rational gas ovens should be tested every six months to make sure they’re operating safely and efficiently.
