A short informative video, dismantling and diagnosing some common
microwave problems. Dan shows you how to
diagnose and points out the most common microwave problems. Microwaves
contain HIGH VOLTAGE. Use extreme caution when troubleshooting and
servicing ---UPDATE 11/1/2013 I have been receiving massive amounts of
EMAIL requesting troubleshooting tips. Please be advised it it almost
impossible for me to help you troubleshoot your appliance unless I am
standing there with you. I get calls and emails all the time wanted
questions answered - there are just to many details and variable for me
to try and diagnose it over email or phone. there are very few items I
recommend servicing in the microwave. Magnetron, door switches, basic
stuff. if it is something else I recommend replacing unit. even if it
does match the décor of your kitchen.
In this video I demonstrate the value of a watt meter and how you can
use a variac to help you test voltage regulators. I also talk about the
serious potential of damaging sensitive electronic components from an
electrostatic discharge. This is something every repairman should be
cautious to about.

When
I first started out doing TV repair I never realized buying original
parts was so important in many cases. I'm not against using generic
parts as long as they work correctly but after a friend of mine was
forced to redo three convergence jobs on his customers big screen TVs I
thought the potential for problems was worth mentioning.
