microwave only half heat sharp 1500w/r-22at

[torxhead]

wondered if anyone had any ideas?
ive got a sharp commercial microwave, customer complains of only having half the power. model 1500w/r-22at.

there are two magnetrons and transformers, like two microwaves in one.

i have disconnected each transformer one at a time and thee doesnt appear to be any less heating power.

wondered if anyone had any ideas?
t.i.a.

When you say doesnt appear to be any less power, have you tested for power output ?
try this http://www.gallawa.com/microtech/output.html with one side at a time disconnected , but please make sure you safely discharge capacitors each time and follow sensible safety precautions

work on it as if it is two micro’s in one.

test one side as u would then the other.

done hundreds of these over the yrs.

there is one way of testing that power is going to the mags that i used to do but dare not post how on here. lol

update.

did the wattage test, strange result.

both magnetrons are working, but only 3/4 power from both.

any suggestions?
could it be the circuit board?

power output is only 1000w. both magnetrons are working
