Question about Sharp R-1505 Microwave Oven

Microwave door alignment is off, will count down but won't cook

The microwave will only cook if I push up on the bottom of the door once it is shut. Otherwise, the door closes, lights work, timer counts down, but the microwave won't cook. I know the door needs to be re-aligned but I don't know how to do that or if it is something that is worth taking to a repair person - should I just scrap it and buy a new one?

If you re-align the door yourself, then you will still have to get the oven leak tested. Just making a door snug does not necessarily mean you have low leakage. Microwaves have such a short wavelength that they frequently behave in peculiar ways.

SOURCE: No Heat

This is probably due to a bad door switch, most likely the top one. The microwave got hot because the cooling fan was not running. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your model number here: http://www3.sears.com/

When you hit Start, does the oven lamp come on but not the fan or turntable?

That would be a problem with the secondary (bottom) door interlock switch or its mount.

This is usually caused by either a bad door switch, a loose door switch mount, or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

You can probably find exploded views and order parts by entering your model number here at the Sears parts site.

The best place to order Sharp parts is Tritronics.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

SOURCE: Sharp R-405KS stopped cooking.

So the oven lamp comes on but the turntable and internal cooling fan do not?

If that is incorrect, please reply back and correct me.

If that's the scenario you have, then you have a bad primary interlock (bottom door switch) or its mount is broken or loose.

We have the service manual for this model and have uploaded it to our site here to help you.

It will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

You will need the
free Acrobat Reader to view or print it in case you don't have it already.

The best place to order parts for this brand is Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

SOURCE: The clock works & counts down but the microwave won't heat

  • Disconnect the power for 30 seconds. After restoring power, do not set the clock.
  • If your model has an ON/OFF clock display, you can choose not to have the time displayed. To choose this option, press the 0 pad for about three seconds. To Turn the display back on, press the 0 again.





Touch the clock pad. Enter in the correct time of day by touching the numbers in sequence. Touch the clock pad again.

Why does Microwave count down but will not run?


Sounds like a door switch is not closing; either primary or secondary. You could have either a bad switch, or the latch assembly is not aligned properly.

There are door switches and one of them is evidently out of adjustment or the little actuator arm on it is.

Microwave won't start


I have the same problem. Is the light still on inside the microwave? Mine is on and the microwave thinks the door is not shut. I took the top off of the microwave and the latch needs to push down on a switch once shut. The latch was reaching the switch, but I think some spring in the door, pushing the latches down, has broken since it reaches the switch when closed but there isn't any downward force to flip the switch.
I am trying to figure out how to repair the latch but if your light is on when you "shut" the door, you may have the same problem.

I would replace the door switches and set up the door gap to 1/8" just enough to alow for a little play.
Setting the door square is acheived by slackening the lower door hinge and re tightening it when the door is square.
Hope that helps.

The door switches are slightly out of alignment. If you run the microwave and shift the door up or down, the micro might begin working..
The control panel must be removed and the door switches adjusted. I would not suggest you doing this yourself, as it may affect the microwave leakage through the door gap.

Sounds like you have a faulty control panel. I would use a meter and test the power from the control board to the magnetron and circuit board. Chances are the control panel is faulty

The timer counts down but the microwave doesnt turn on.


I have a FNCB115GC Microwave problem. The microwave has a icon on the left hand side of the panel that looks like a opened book on a stand with lines on top. This is best that I can descibe it. The microwave turntable does not move or the microwave does to come on but the light comes on and the timer will count down. I have cleared the microwave and unplugged it with no results. Please help. Thanks in advance.

Same - the counter counts down, but doesn't cook.


Yes your door isnt aligning right when closed and the lower interlock isnt being made when shut. Look and see if where the door pivots if it is broke or sagging down.

Microwave turns on and counts down but won't heat up/cook


Ok just figured this out! It is a problem with the alignment on the lower door switch. I took the cabinet off and lifted up on the door switch slightly and voila! It works. You could probably fix this without taking it apart, just lift up on the door ever so slightly. I hope this works for you.
