Larry July 09, 2026 for Model Number Hbl5650uc/06 Lower oven locked by its self ? Won’t unlock happened when not in use ?
1 Answer If the lower oven door on your Bosch HBL5650UC/06 locked itself while the oven was not in use, it is usually caused by one of these issues:Control board glitch (most common) – The control may have mistakenly energized the door lock motor.Door lock assembly or lock switch failure – The lock motor or position switches may be stuck, making the control think the oven is in a self-clean cycle.Faulty electronic control board – If the lock continues to engage by itself, the control board may be sending power to the lock motor when it shouldn't.Here are a few things I'd recommend trying:Perform a hard reset. Turn the oven off at the circuit breaker for 5–10 minutes, then restore power and see if the lock retracts.Check the display. Does it say "LOCKED", "SELF CLEAN", or show any error codes? That can help narrow down the cause.Try starting and then canceling a self-clean cycle. Sometimes the control will drive the lock motor through a full cycle and release it when you press Cancel.If the door remains locked after the reset, the next step is to determine whether the control board is continuously sending voltage to the door lock motor or if the door lock assembly is mechanically stuck. That test requires working with live voltage, so use appropriate caution.Live Power Warning: Extreme care should always be taken to protect against electric shock, which could potentially result in serious injury. Please do not test live voltage if you are uncomfortable using a multimeter around live voltage. If you'd like to know more about how to use a multimeter, we've put together a comprehensive tutorial for you, so check out the link in the description.A couple of questions that will help pinpoint the problem:Is the upper oven operating normally, or is it affected too?Is the lower oven display showing any error codes or messages?When you try to unlock it, do you hear the door lock motor running or clicking, or is it completely silent?

Scott July 18, 2022 for Model Number HBL5650UC/03 I've seen a few posts and questions with the same issue of mine where my Bosch oven keeps resetting. I have replaced the control board 12022213 twice (I thought my first replacement one was bad). The resetting issue persists. Would you have any further recommendations for repair? As it stands, my oven is unusable. Thanks.-Scott
1 Answer Scott, the cooling fans would need to be checked to ensure they are allowing airflow during operation. If they are, it is likely that the interface control 00686560. Read More...
Steve December 23, 2019 for Model Number Bosch HBL3550UC/08 About a year ago there was an error message on the display, so I replaced the control board. After that the top oven never heated to correct temperature, so about a month ago I replaced the heat sensor/thermostat. Now it does reach the temp setting, but takes 30 minutes to preheat when oven is empty. However, when trying to bake something, the oven never reaches the temp setting. Both upper and lower elements are working. The bottom oven is functioning properly.
Dan August 28, 2016 for Model Number ME302EP/07 How hard is it to replace this part? Do I need special tools? Thanks, Dan
1 Answer Dan, Other than a set of "Torx" drivers ot "Torx tips" to remove the panel screws, no special tools are required to repair your wall oven. " How hard is it to replace this part ?" It's not that hard at all, the hardest part will be removing the oven from the wall. " The PC control module (relay board) is serviceable from the top access panel after sliding the oven out from the wall ~16 inches. With the unit pulled completely away from the wall, the following components are serviceable from the top after removing the top panel: ? Halogen light transformers, ? Terminal block, ? Power supply" So make sure you remove power to the wall oven before you start . " To access the PC control module, pull the unit out from the wall 15-16 inches, and remove the access panel (3 T20 screws) on the top of the unit." Read More...
