Christmas is the busiest time of year for most commercial kitchens. Office parties, festive menus, private bookings and back-to-back services all put extra pressure on your equipment. In many kitchens, the Rational combi oven does more of the work than anything else on the line.
If your combi breaks down in mid-December, you lose more than one appliance. It can mean cancelled covers, a rewritten menu and a stressed team at the worst possible moment. Getting it serviced now is the simplest way to avoid that.
Why Service Your Rational Before Christmas?
A pre-Christmas service from RTC Technical helps you:
- Maintain optimum performance, so your oven heats, steams and cooks exactly as it should when you’re at full capacity
- Reduce the risk of breakdowns by spotting worn parts and early warning signs before they cause a failure during service
- Ensure food quality and consistency, so every plate leaving the pass is cooked to the same standard, from the first sitting to the last
- Keep your kitchen running smoothly through the Christmas rush and into the New Year

As an authorised Rational service partner, we have direct access to Rational’s knowledge and support. Our engineers carry out a thorough check of your combi, including:

Warning Signs to Look Out For
If you notice any of the following, book a visit sooner rather than later:
- Error codes or messages on the display (see our Rational error codes guide)
- The oven not reaching temperature or taking longer to heat up
- Water leaking from the door or underneath the unit
- Uneven cooking results or inconsistent steam
- Failed or interrupted cleaning cycles
Don’t Leave It Too Late
Diaries fill up quickly in the run-up to Christmas, so the earlier you book, the easier it is to fit your service around your trading hours. If something does go wrong over the festive period, our emergency Rational oven repair service is available 24/7, 365 days a year.
Need more than your combi looked after? Our planned preventative maintenance covers the rest of your kitchen too.
