Questions & Answers

For Whirlpool Waveguide Cover (Part Number: OEM18144159)

1 Answer

Joe, To remove the cover you will want to use a putty knife to pop it off. If you have a plastic one it will work better for not scratching the paint. If you do not have a plastic one put some tape on the blade of it to make sure that the paint does not get scratched.

Hello Susan, When this occurs, it is usually moisture that has gotten behind or on the cover. The moisture absorbs the heat and causes the issue. You will need to replace the cover W11087199 and inspect, clean, and dry the area under the cover before installing it since this can damage the magnetron. Be sure to unplug the unit whenever removing any cover to prevent electric shock or electrocution.

Hello Susan, You would just pry the cover off and install the new one. The cause for the hole would either be caused by moisture getting into the area or the magnetron is starting to fail. If moisture has gotten into the end of the magnetron, this would cause the magnetron to fail. If you don't replace the cover, the magnetron will fail prematurely.

Shirley L for Model Number KBMS1454RSS0

I see that I can get the part Covr-Inlet OEM Part Number AP3865977 for my Kitchen Aid microwave KBMS1454RSS0. My question is how do I replace it ... it does not look like there is anyway to remove it from the ceiling of the microwave. Is it pried off? The reason for replacement is a hole that formed from being melted. Is it safe to use as is? Was the melting caused from heating something to high of heat or from something within the microwave (the magnitron? ) Any advice would very much be appreciated.

Hi Lonestar. Tricky one, If the magnetron is still heating well, then is should be OK. If the inlet cover melted then it is safe to assume the heat was at a higher setting and the heating occured towards the interior top area. This part # is W11087199. Thank you.
