Where can you take your microwave to get it fixed inexpensively? It's cheap as it is, I don't want to pay a lot for repairs.

I suggest you look into https://a-repair.com/brampton-appliance-repair/. It's a really inexpensive option for repairs, with great service and quality service for your appliances. I've fixed my refrigerator from them before, and I can say that after their repair, it worked for quite a while before I sold it.
