What is the voltage for the high volatge transformer supposed to be? The microwave does not heat.
Answer Hi Ryan. Usually when there is no heat in a microwave, the magnetron , diode and capacitor are defective. The magnetron part # is 5304441846.the capacitor part # is 5304455389. The diode part # is 5304461263. The primary side has to receive 120vac to the transformer, when the door is closed in normal operation. You CAN-NOT measure the secondary side of the transformer because of the UN-SAFE HIGH VOLTAGE upwards of 44,000vac. AGAIN - for your safety , DO NOT ATTEMPT ANY HIGH VOLTAGE MEASUREMENTS!!!!!! The transformer part # is 5304453726. Thank - you.
