My hotpoint RB757WH5WW electric range display and oven are no longer working. My husband was being helpful by trying to replace my oven light bulb. He heard a loud POP and the display went blank.

Hello,

If I understood your question correctly you are trying to replace the Hotpoint Oven door and cannot understand how to do it. Since you cannot specify the model I am posting a video link which will show you how to remove and replace the hotpoint oven door for a model older like yours.

Thank You for contacting Fixya.com

you will need to replace the control board that contains the clock readout,any power surges ruins these electronics instantly,this can be replaced by removing the rear cover on the back of the unit and remove screws securing the electronic module

mam please check the thermostat and its settings.

Reolace the electronic oven control.

Try resetting the house breaker.

if the flash came from the back of the unit it was probably the control board. and you would need to replace the control board

http://www.pcappliancerepair.com/model-display.php here is a link to your oven and it is shown in an exploded view. You will need to unscrew the cover from over the light bulb and then unscrew the bulb to replace with same. Hope this helps..

I pressed the lock icon on the panel and held it for a few seconds and the display cleared.

you need to replace the oven ignitor coil.

The problem is almost certainly on the control panel, which we repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This often can affect the exhaust fan operation, too. The lights and fan can be inopoerable or stuck on.
