Our top oven inner door glass for the model 720EF shattered and we need a new one. The number is 059040415.D you sell such a thing and if so how much?

Yes you can, your best bet. Try to go to manufacture of your stove.
If they discontinued then try the web

First things first. The top oven lights ONLY come on when the top oven is switched on. Operating the grill DOES NOT turn the lights on. If you wish to see what you are grilling, you have to turn the top oven control knob on to its first position as well as turning the grill on.
Secondly, the grill only works when the door is open. The grill does not work when you shut the door. When you open and shut the door, you should be able to hear the microswitch operating. It is located in the right hand side of the cooker, between the inner and outer panels - you cannot see it. I haven't seen the switch first hand but they normally come with an arm that contacts the door mechanism and the door mechanism operating, causes the arm to move, which causes a button on the switch to move and make the circuit. It has been known for the arm on the microswitch to bend with use so it no longer works correctly.
If you have checked all above and you hear the switch operating, then it could have failed. They are quite common, so if you can't get one from STOVES, try espares or someone like Maplin or RadioSpares.
The get to the microswitch you have to take the oven out of the housing and then take the right hand panel off. You should then be able to see it and check its operation.
All the best

You can try espares. If it is not listed, there is normally a help section where you can send in a request. You will need the model number as well to ensure you obtain the right version. (It could be something like 059040415).
If you want to check what the oven is doing before buying the new parts, Lakeland do a reasonably priced oven thermometer, I think about 4 or 5 pounds to see what temperatures it is reaching. Also check the thermostat sensor. It is the long thin cylinder in the top right hand corner of the oven. It should be clean as a whistle and not covered in grease gunge etc. If it is, this could cause incorrect readings. Don't attempt to clean it manually as it is quite fragile, especially the connecting wire. Leave the sensor in situ and use a paste on oven cleaner which really works ( from Lakeland) and follow the instructions. it should come up bright and shiny. Best of luck.

First things first. The oven element is totally separate to the grill element. The clock has to have a time set for either the top or bottom oven to work, whereas the grill will work without the clock being set.
The control knob for the top oven is the ONLY control that will turn the top oven lights on, the grill does not turn the lights on. ( If you want to watch your toast, you have to turn the top oven switch on to the first setting as well as operating the grill control).
To prevent the grill being operated with the door shut, there is a micro-switch on the door hinge that allows the grill to operate ONLY when the door is down. The grill control also does not illuminate unless the door is down. There are two options on the grill control - right or left. One way is the inner element only and the other is both inner and outer ones.
So if you have done all that and it still doesn't work, then the micro-switch could be faulty.
Best of luck

Try espares. If the part is not listed, there is a contact on the website to obtain a quote for a part. Of course once you have the part number you can try elsewhere.

Hi and welcome to FixYa I am Kelly.

Since you did not include a model number this solution will be from the hip as I can not refer to any manuals to assist you. Most ovens the oven door comes off by tilting the door out to the first stop and then lifting is vertical inline with the position of the hinge at the bottom of the door. Some of them may have retaining screws on the inside of the door to keep the door attached to the hinge area that must be removed FIRST. The hinge itself should stay attached to the oven.

I can probably provide you with a source (Maybe more than one) for the door glass if you respond with a model number,

When you attempt to take the door apart lay it down on 2 rugs so you do not scratch it. Use some blocks of wood UNDER the rugs to prop the door up so as not to damage the handle.

The door glass is replaced by removing the screws from the indide of the door. Sometimes you have to remove the trim pieces in addition to the multiple door panels. Everything is done from the inside of the door. You must take out the inner panel, Then the inner glass, then the spacer, the insulation if any and finally the outer door glass. Reassembly is in reverse order. Outer glass, spacer, insulation if any inner glass, the inner panel and re-install the trim if you had to remove it.

Thanks for choosing FixYa.

Unfortunatey, it happens quite frequently, there is no one reason for it to do so.
The only solution is to replace it.
Over a number of years use, the glass looses it's properties, and this is what can happen.

Try ESPARES. If it is not on the website, ask for a quote.

It isn't that tough to change the glass assembly. Most of the Frigidaire have 4 screws that hold the front of the door to the inner part- sandwiching the glass in between. It is only sold as a unit- 2 glass pieces, assembled with an aluminum frame. Call All brands Appliance parts at 508-587-7100 and they'll get the part out to you. (Tell them Greasy Wheels sent ya, they'll take good care of you.) The most common reason the glass breaks, is a scratch in the glass. Sometimes it's just a dragged pan, other times it's from cleaning it with a sharp instrument. Don't do that....

This is not a job you should do. Microwaves are dangerous things and can cause injury. An improperly fitted door will leak. A new door, installed and checked out by a technician is needed here The economics are beyond my area.
