Daewoo KOR-7LREM Retro micro
Sporadic:sometimes heats up the food & most of the time doesn't heat like it should-have to add time to the recommended time but getting increasingly unreliable.
Does it have a turn table that spins your food container? If so, does it turn? If not, you are getting a solid directed beam of microwaves focused on one part of your food leaving the rest of it ignored. If it doesn't have a turn table, it will have a wave spreader inside which is nothing more than an aluminum fan that is sometimes driven by a small motor and rubber belt. You won't see this as it is inside the chamber that contains the magnetron that generates the microwaves. These belts can break allowing a solid, focused microwave beam to shine on your food rather than be distributed around the oven, again, leaving the rest unwarmed. If this is the case, using the oven can damage it over time. If you don't know what you are doing, DO NOT try to repair it yourself!!! If you don't get the outer casing back together properly, you can expose yourself and / or your family to dangerous amounts of microwave radiation. You should take it to a qualified service center for repair but I would venture a guess that it is already damaged because of your statement "but getting increasingly unreliable". Even if it isn't damaged, it will probably cost you more in labor to fix it than it would cost to replace it. Good luck.
