I'm worried that microwave is ON when door open. This unit comes with a metal rack not installed so I think testing it by inserting stainless pan inside open door won't produce expected sparks. Can you help? My thanks. JBest
Check microswitches in the latch assembly.

I assume you're talking about the spring that keeps tension on the door hooks (latch heads, as they're called by Sharp). When you shut the door, the "hooks" are held down by this spring to actuate the door switches. To fix this, you'll have to separate the door panels. You can download the service manual from my Web site. There's a loop built into the latch head assembly and sometimes the loop breaks. If so, you can drill a tiny hold in it and reattach the spring there. There may also be a loop on the innner door panel to hold the spring. That one can break, too. If it's broken, you'll have to find a way to secure the spring to the panel. If the panel material is thick enough, a tiny screw eye could be inserted, then epoxied overnight to secure it. I've attached a diagram to this message that should help you. If that doesn't help you, I have the service manual for the R1600-series microwaves on my Web site at: http://www.microwavedisplay.com/R1610.pdf Repost if you need more help.

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.
Even though a door switch clicks, it may still be bad inside.
Switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

est the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.
Thediode
and capacitors can br tested. The capacitor must bealloweddischarge
before testing, or you risk to get electrocuted, evenifpower is off.
Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.
