Disconnect the oven’s power source. Locate its fuse on your fuse box. If you can’t find it, contact an electrician to help you turn it off. If your home has recently been in a flood, have the electricity turned off in the entire home before you attempt to go home and fix and salvage items. This is extremely important, as the water and electricity could pose a serious hazard.
Unplug the convection oven and move it to a dry location. Prop the door open and help dry it out by placing a fan directly in front of it. It could take as much as a week to properly dry out the oven.
Clean the oven’s interior while you wait for it to dry completely. Oftentimes, water damage can leave behind unpleasant smells or even mold. The North Carolina University College of Agriculture and Life Sciences says never to clean the oven with a hose. A hose could add to the water damage, as the spray can seep into areas you can’t see to clean. Instead, use a wet rag to remove debris in the oven. Disinfect the oven with bleach. Use ¾ cup of bleach to each gallon of water. This mixture will help prevent the growth of mold. If you’re struggling with odor in the oven, add vinegar or baking soda to water and scrub the oven out.
After a week, plug the oven back in. If it’s still not working, let it sit for a few more days with the fan. After that, contact an electrician to see if the wiring system is ruined.
