As you look into the microwave ,on the right , there is a small grilled area with a light
and just above and towards the back there appears to be a fan . At least that is where the noise is coming from. Why do we want to replace the fan ? Because we have gone however many years it is since we bought this appliance with relative quiet and
my wife says she can't live with the present noise level . I tried putting the vacuum hose
to the face of the grill . The fan was quiet for about ten seconds then reverted to its
previous noise level. Also we were referred to an outfit by the local Panasonic small appliance distributers . They said (a phone conversation ) that it probably was a fault
with the fan ." Bring it in and we will put in a new one."
Okay, I am not second guessing you but the most common problem I find with the noise of the convection function of the micro/convection is actually the belt for the fan. What happens is throughout the years the rubber belt stretches and when it runs it flops and hits the metal that make a bad noise. Now the fan you are talking about is held on by a nut. If you decide to replace it you need to hold the fan blades while you loosen the nut. To get to the belt you will need to remove the screws off of the back of the microwave. Then with a little uummpphh pull back and up a little to take the cover off. I am going to send you a link to a diagram that shows the convection area. The belt I am talking about is #39. Hope this helps and le me know how it goes.
Thank you , but I am still left with wanting an answer to my original question which
was "How do I get the microwave out from its housing ?"
It is built in above our main oven . I was told one lifted up the front and it should pull out.
This I have tried without success. It lifts up easily enough but I cannot move it forward How much force should be required ?
I have tried the little extra ummmph and taken a closer look at things.
It would appear the moulding around , or at least at the bottom , must come off
because one can't lift the oven high enough to allow the rubber feet to pass over
the moulding . I would expect this to be clipped on somehow , as I see no evidence of screws , but suspect a probable very simple operation for one experienced is a major challenge to the uninitiated. It can't be a question of brute force , surely?
