Question about Whirlpool RMC275PD Microwave Oven
Whirlpool Gold Built in Combo. GMC305PDB5. Replaced the diode because of troubleshooting site. Still exhibits the same problem. Is this the capacitor or the magnetron? The capacitor looks fine, but the smell reminds me of the smell of the oil burning in the capacitor. However with my limited knowledge the capacitor seems to test correctly. Any ideas on how I can determine whether it's the magnatron or the capacitor. Thank you in advance for your help.
should be a "mini-manual" (tech sheet) hidden inside the unit behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting, testing, and locating components.
With a smell present, I would not suspect the capacitor, but here are some links you or someone you know can use for test help, but read the safety warnings first:
http://www.gallawa.com/microtech/diode.html (if it is NOT shorted, it's probably fine)
http://www.gallawa.com/microtech/mag_test.html (continuity can be good even though it is bad!)
I would most suspect the magnetron or transformer.
