Superior Service has specialized in Convotherm combi oven repair across California for over four decades. We know the C4 EasyTouch inside and out, from the ConvoSense controller quirks to the OES series steam generator failures. Our techs carry OEM and approved aftermarket parts for common failures: steam sensors, door microswitches, drain pumps, and fan motors. We get that a down combi oven means your kitchen is limping along on backup equipment or worse, losing ticket times. That's why we prioritize combi calls and keep our vans stocked for first-trip completions.
The C4 EasyTouch loves to throw ConvoSense errors when the water hardness sensor gets fouled or the steam probe calcifies. OES 6.10 and 10.10 units see door switch failures and drain pump clogs from grease carryover. The mini models are great for tight kitchens but the smaller boiler means scale builds faster. We carry descaling kits, replacement probes, genuine Convotherm door gaskets, and the tricky little drain valve assemblies that clog. Most calls we're done in under two hours because we've seen it before.
Average combi oven repair: $400–$800. Average day of lost revenue with a down unit: $500–$2,000. Getting it fixed today instead of waiting 2 days for the manufacturer pays for itself before we leave the parking lot.
