My microwave is cutting out before the time I have put in

This answer was rated:

Good morning. My microwave is cutting out before the time I have put in (apart from it will do 1 minute when 1 minute put in). When you open the door it is hot inside the microwave, however the liquid is cold. Can you tell me what is wrong

Hi, thank you for choosing Just Answer, my name is ***** ***** I will help with your query today.

How old is the microwave, and if when the microwave is running do you see the table turning inside?

Purchased in 2002. Turntable does revolve

Is there a problem James, am I still connected to you

Sorry for the delay in responding, have you checked the microwave has air circulating around it (for example the air vents at not blocked)?

Customer: replied 16 days ago.
that is all ok. Have just put 1/2 pint water in for 3 mins on medium and although it didn't cut out it has only come out lukewarm

Ok this points to a fault on the Hight Voltage circuit within the microwave.

Looking at eSpares, Ransom and other firms the HV PCB is showing as obsolete, the typical cost would be around £70. The HV PCB regulates power to the magnatron, and its likely this or the HV capacitor which has failed.

Based on the age of the appliance and parts being obsolete, I would recommend replacement rather than repair.

Is there anything else I can assist you with?

Sort of thought this would be the response because of the age of the equipment. Thank you for your confirmation and your speedy reply
