A speed or convection microwave puts a second heat source into the same cavity. Behind the rear wall or above the ceiling sits a heating element with a fan that blows hot air around the food; some speed models add halogen lamps or a browning element that sear the surface, and all of them add a temperature sensor, relays on the board and a longer list of modes. The magnetron still does the fast heating, and in combination modes both run together. That shared cavity means one half can fail while the other works: a unit that reheats a mug but will not bake a potato has a problem on the browning side, while one that browns but leaves soup cold has a microwave-side problem. Convection elements open like any heating element, the hot-air fan motor seizes, a sensor drifts and the board overshoots or undershoots the setting, and a relay that sticks can leave the element on. Because these units run much hotter than a plain microwave, their cooling fans and thermal cutouts matter more, and grease from roasting builds up on the rear panel and the element. The technician tests each heat source separately with the capacitor discharged before any cover is opened, then checks the combination mode with both running. How the visit goes ### What it usually costs Moderate to highest · Convection element, hot-air fan, lamps or sensor A temperature sensor or a relay is a modest part. A convection element, a hot-air fan motor or a set of halogen lamps for a speed model costs more, and a board made for one premium model sits at the top. ### Answers 6 problems Microwave Runs but Food Stays Cold What a Microwave Error Code Is Telling You · Microwave Shuts Off Before the Timer Ends · Burning Smell From a Microwave · Microwave Fire: Smoke or Flames Behind the Door · Microwave Display Dark, Dim or Scrambled ### Comes up most on Built-in microwave Microwave hood combination · Countertop microwave ## Speed and convection microwave repair, step by step. Run every mode again, show you the cavity reaching its set heat, and explain how to keep the rear panel clean. 01 Run plain microwave power, then convection or bake, then a combination or speed mode, and measure what each one delivers. 02 Note any code, and look at the rear panel, the element, the lamps and the cavity for grease buildup or burn marks. 03 Cut the power, draw the unit forward if it is built in, discharge the capacitor, and test the element, the hot-air fan, the sensor and their relays. 04 Replace the failed element, fan motor, lamp, sensor or relay, and check the cooling fan and thermal cutouts that protect it. 05 Run every mode again, show you the cavity reaching its set heat, and explain how to keep the rear panel clean. ## The problems it answers. 6 of them, from microwave runs but food stays cold to microwave display dark, dim or scrambled.

Is it broken? Often it is grease baked onto the rear panel, the element or the cavity walls burning off, especially after roasting. Clean the cavity the way your manual describes and run a short convection cycle empty only if the manual allows it. Smoke that keeps coming from a clean cavity, or any flame, means stop it, keep the door shut and book a visit. ### Why does my speed microwave bake but not reheat? Baking uses the convection element or lamps, while reheating uses the magnetron. When only one works, the trouble sits on one side of the cavity: the magnetron and its high-voltage parts, or a door switch the microwave mode checks, are tested for a unit that bakes but will not reheat. ### Is a speed or convection microwave worth repairing? In most cases, yes. These are built-in or premium units that cost far more than a plain microwave and fill a matched opening. Elements, fans, sensors and relays are ordinary repairs. The exception is a discontinued model whose control board is no longer available, and that is checked before anything is ordered. --- **[Read on the site: Speed and Convection Microwave Repair](https://microwaverepair.center/services/speed-and-convection-microwave-repair/)** **[Book a visit with MicrowaveRepair.center](https://microwaverepair.center/schedule/)**
