BTW APollo says they can fix your unit
From Apollo website
"MICROWAVE OVEN REPAIR
Apollo can Repair or Replace any Microwave Brand!
Call us for a Free Diagnosis and cost estimate.
Don't pay a service company $100-$150 to come and diagnose your problem. In 90% of the cases, they will not have the part to fix your oven and will charge you a second service call when they come back and install the part. You will end up spending $500 or more and end up with a 5-10 year old oven. Please call our customer service center at 800-330-9707. You can also email us: sales@apolloworldwide.info and we will provide whatever you might need."
