Bosch Oven Not Heating
Oven Not Heating is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Surface-run supply in a house with no wall voids
Power and gas in these kitchens are often routed around rather than through, and a long or shared run shows up as an element that heats slowly.
A failed bake or broil element
The most common cause of a full loss of heat in an electric oven.
A drifted temperature sensor
Electronic sensors drift out of spec gradually, so the oven can run well off-target without any error showing.
Local conditions that matter here
Post-and-beam construction leaves very little wall cavity to run anything through, so gas and power in these kitchens are often surface-run or routed the long way. That matters when a fault turns out to be upstream of the appliance rather than inside it.
