David Page for Model Number GE Spacemaker XL1800 My microwave isn't heating and from everything I can find it is a bad H.V. Diode and H.V. Capacitor. The paperwork with the MW list two different part numbers. Is there a difference between the two, there is a huge price difference. SEC PARTS NO. GEA CAT-NO. H.V. Diode. DE91-70063A WB27X1160 H.V. Capacitor 2501-001011 WB27X10011 Does it matter then as to which part I were to order?
Answer David, Yes there is a difference, they are two separate components, and perform different tasks. The WB27X10011 capacitor Increases or "steps up" the voltage to the magnetron. The diode AP2026385 directs the "excess"/stray voltage from the hi voltage components to chassis ground and dissipates the voltage into the electrical system. The diode is also a "one way" direction "switch", it will allow the voltage out of the circuit, but should not allow voltage to flow back into the machine. It's usually best to replace both parts at the same time, but that will be up to you. Thanks, Read More... Answered by AppliancePartsPros.com | Friday, April 14, 2017
