The Repair-Ungarbage subforum seemed like a good place for this query.

I'm trying hard NOT to discard of a countertop air-fryer oven (Cuisinart) that appears to just have a bad door switch (turns the unit off when the door is open, turns it back on when the door is closed).  It has a lot of screws ostensibly holding on the main housing. But when I remove all of the apparently necessary screws, it still seems as though the housing is stuck tight in a place where no screws are evident......and right where the door switch is located!  Does anyone know if it's common to use either spot welds or high-temperature glue is such places to keep the housing from coming off?  I start to wonder about taking some metal shears to the housing and just leaving the ugly hole there when done.  (It's off warranty, so that would not be an issue...).   I can't seem to find a repair manual for it anywhere.  Opinions?  I just hate the thought of adding one more appliance to the scrap heap.....  Thanks!

You've got "Microwave" in your title but refer to an air fryer in your post.  I've never seen an air fryer combined with a microwave, but the world is large and there are many things in it that I have not seen. "There are more things in heaven and Earth, Horatio, than are dreamt of in your philosophy." If your unit genuinely contains a microwave cooking element, it's normal for microwave ovens to be assembled in some difficult-to-disassemble manner.  (Or so I have been told.)  This is because the housing is an important part of the safety screening (metal, Faraday cage) that prevents you from cooking your face or internal organs when you stand next to your unit waiting for food to be done.  If the housing were easily removed, some genius would inevitably try to operate the unit with the housing off while peering intently at the works, and then his descendants would sue the manufacturer for his fatal case of cooked-face.

If your unit does not contain a magnetron, then I got nothin'.

My bad....attached is a stock photo.  I already re-assembled mine with the screws since I was getting nowhere.  In the photo below, you can see where the little switch on the right-hand side is that gets pushed in when the door closes.  Yeah...I guess I understand the reasoning behind the "No Entry" philosophy with these units.  I just cringe at having to send it back to the manufacturer when it just went off warranty and could be an easy fix on my own.....or at least I envision it being easy... :-)  Let me know if you want additional photos of the broken appliance that may be of use.

I can't read the dials in that photo.  It doesn't look like it has microwave function, due to the metal-appearing basket and shelf, but can you confirm?

I wonder if the switch has a collar holding it on (and possibly grounding it...)

Sorry...my original addition of the word 'microwave' was in the probably false assumption that most of these types of counter-top appliances perhaps had the same general sort of housing.  So if that is not the case, then disregard the reference to that and my apologies for the confusion.  The back of the unit and along the bottom edges is where the majority of the screws are located.  When I remove these screws....with the intent of removing the exterior housing.... I can separate the housing from the unit along the *back* of the unit, but not along the *front* of the unit, which has me confused.  It's almost as if along the front of the unit they used some other sort of bonding principle because there are no other obvious screws along that front edge where the door is located that would be holding the housing into place.  And there is a seam along that edge where the exterior housing meets the metal through which that button is protruding.  So I was thinking this was separable from that metal, but it appears not to be.

No worries!  I just wanted to be 100% sure, because the safety implications of digging into a broken microwave are so severe, I was afraid that some people with appliance repair knowledge (not me!) would be reluctant to reply in your thread.  I have taken the liberty of changing the title of the thread, just to take the whole "microwave" danger-spectre off the table.

Can you get access to that switch from behind by taking off the rear panel?

I'll take a look at that this coming weekend.  I suspect it will be pretty narrow access with the oven chamber that close to the housing, but will see what I can see.  Thanks!

You did check the bottom for screws, right? Including screws that hide under threatening stickers? The ones that say "Violating this appliances warranty will make your ears fall off, don't do it!!" Really seems like it should come apart. Most things like that do. I have scavenged the cabinets from several things of that ilk, never had as issue getting them off. Check in the feet too, those screws are sometimes structural.

I'm guessing clips, possibly nasty one way clips. Makes assembly a snap! If nothing else works, take a pry bar (screwdriver) to the edge of dial housing. If any gap opens you may be able to see what the attachment is.
