Bulb replacement


Is it an over-the-range (OTR) microwave or a countertop microwave? If it's an OTR microwave, are you talking about the light(s) on the bottom of the microwave, or the one that lights up the cavity when you open the door or run the microwave?
If it's an OTR microwave, and the cavity light is burned out, you MAY be able to access it by removing the grill vent by removing the 2 to 4 screws above it. Then, depending on the model, either slide the grill vent to the left and pull it out, or else pull out the top part of it first. Then, if there is one, you may see an access cover behind the grill vent. Unplug the microwave, then remove the 2 screw that holds the access cover in place, and lift up and remove the cover. You should now be able to get to the light bulb.
If it's a counter-top microwave, you will have to remove the complete cover by removing the screws on the back, and possibly a couple of the sides. Note, 2 screws are special security screws to prevent the casual customer from fixing his own microwave oven! UNPLUG THE MICROWAVE FIRST, then remove the cover screws. Slide the cover back about 1/2 inch, and then it should come completely off. You should now be able to see the light bulb to change it. Then reverse the process to put the cover back on. I hope this helps.

Spontaneously stops working and then comes on after 5 minutes. Why?


Sounds like the magnetron is overheating. There is an automatically-resetable thermal circuit breaker attached to the magnetron. Most likely your problem is caused by either a cooling fan that is not running, or is running too slow (caused by gummed-up bearings). In some over-the-range (OTR) microwave ovens, the exhaust fan is run at a slow speed to cool the magnetron, and if it's bearings get gummed up, it won't run on the slow speed. But if it's a new OTR microwave, then the exhaust fan may be pointing the wrong way. (It is rotatable, depending on the installation). For example, if it is pointing up, but you don't have an exhaust vent over the microwave, then the air has nowhere to go, and the magnetron will overheat.

Internal fuse


Is this an over-the-range (OTR) microwave oven or a counter-top model? Assuming it is an OTR model, your can get to the fuse by first unplugging the microwave, then removing 2 to 4 screws over the grille vent. Remove the grille vent. Depending on the model, you either slide it to the left a little bit (1/4 inch) then pull it out, OR tilt out the top of it followed by the bottom. Now you should see 1 screw that hold the top of the control console in place. Remove it, then lift up on the control console to get past the tabs, and tilt out the top. Now, depending on the model, you may see the fuse behind the control console, or if it's not there, then remove the 1 or 2 screws that hold the metal grill vent that's located above the control console. Remove that metal grill, and your should see the fuse behind it. Sometimes that fuse blows for no good reason, other times it blows because you have a shorted high-voltage capacitor, or you may have a sticking "monitor" door switch.

How to replace lightbulb


Is this a countertop microwave or an over-the-rang (OTR) microwave? If it's a countertop model, you need to completely remove the outer case to get to the lightbulb. If it's and OTR microwave, there usually is an access cover located behind the grill vent. You can remove that grille vent by removing the 2 to 4 screws above the grill vent. Then either slide the grill vent 1/4" to the left to remove it, or else (depending on the model), just pull out the top of the grill vent, followed by the bottom. Then you should be able to see the lightbulb access cover. Usually there is 1 screw that you have to remove. But unplug the microwave before you to any further! Now remove the screw, lift up and remove the cover, and you should be able to get to the light bulb.

Can a Kenmore Microwave oven Model 401.8504*, 85143 be put on a counter top and used?


Most over-the-range (OTR) microwave ovens have the exhaust fan funning at low speed when the microwave oven is working. This is to keep the magnetron and electronics cool. And it sucks air in from the bottom, so if you just place this microwave flat on the countertop, it won't be able to suck air in, and it could overheat if you use it for more than just a few minutes. But if you can put it on some boards or some sort of grill so air can get to the bottom, then you should be okay to use it as a counter-top model.

How does this microwave exhaust system work. The installer did not use any duct work, so is the exhaust internal somehow? There is no grill on the exterior for exhaust


The exhaust fan appears to intake through a louvered vent in the bottom rear of the microwave case and output through a grease filter near the top front center of the case. You may be able to see some vent holes along the top of the case though these might be obscured by the manner in which the microwave was installed. You should be able to pop off the front panel that runs above the door but you'll need to consult the owners manual for specific instuctions.

Cheers.

Making a sound (I think from the fan) when operating


If it is only when he exhaust fan is on, something is in the fan. Remove the grill and investigate. If it is from the Magnatron fan you will have to remove the front panel.

Can't remove the vent grill


Two problems found. The electrician that installed the micro. installed it incorrectly. The fan was supposed to be turned so that the exhaust would go through the pre-installed duct in the wall. To remove the grill, there is two screws on top of the micro. which have to be removed. The builder put in a deeper cabinet that covers the screws because it looks better. To fix it I have to drop the micro, take off the grill, clean it and all the grease off the micro., replace the charcoal filter, turn the fan so it will exhaust through the duct and reinstall the micro.
