Thermador Appliance Repair in Markham

The Thermador call we get most often in Unionville arrives the morning after a self-clean, and the double wall ovens are the ones that suffer. In a stacked pair the control electronics sit in the bay between the two cavities, so running the pyrolytic cycle in the lower oven soaks the board from underneath for three hours. The upper oven is what stops responding, which sends people looking at the wrong appliance.

The doors are the second casualty. Hinge springs on these ovens are wound for a heavy triple-glazed door, and at cleaning temperatures they relax slightly. Do that a few times and the door sits a millimetre or two proud at one corner — enough that the latch no longer confirms and the oven refuses to start. It is not a broken door and it does not need one. Hinges get replaced or reset and the strike plate adjusted until the latch confirms every time.

Our standing advice for these built-ins is to clean at a low ambient, with the kitchen ventilated and nothing scheduled in that oven for two days. Most Unionville kitchens are tight, sealed and warm — comfortable for the house and hard on the appliance.
