Just wanted to add this has happened to me too. I've started a brand new save, no mods or CC installed, and the Sim is in a residential rental. I recently bought him a new stove, deleting the one that came with the original lot, and the following sim day the Explosive Malfunction event started saying the stove, grill or oven needed repairing or replacing. There were no other ovens, stoves, or grills on the lot or shared space and the new stove was in perfect order and couldn't be repaired. I also couldn't replace it as the option for Build/Buy was greyed out.
I can share the save file with the event in progress if that would help.
