Question about Sharp R-1610 Microwave Oven

1 Answer

Fan comes on when slight opening pressure is exerted on door handle.

I have two Sharp R-1611 units and both exhibit the same problems.  The plastic housings and doors are cracking in multiple locations and the fans in both units come on when pressure is exerted on the door handle, but before the door actually opens.

Re: Fan comes on when slight opening pressure is exerted...

The door frame and seal damage has put the relation of the door latches and the interlock assembly out of adjustment. If after disassembling the door it is found that the latch assembly is good, replacement of the door frame/seal might be all that is required to return the oven to normal operation. After reassembly, it is highly recommended to have the oven's emissions checked at an authorized service center for any leakage around the door seal area. The service center might also need to adjust and set the interlock assembly for correct operation also.

I have a Sharp Microwave R-530E-S, when I put power on it it the interior light comes on and a fan (I think it's the cooling fan?), when I open the door the fan switches off and obviously the

First of all, you should not open the door when the unit is in operation. This may cause this problem. The light should come on when the door is open, even if interrupting a cook cycle. I'm not sure then that I am understanding the description of the problem.

Sharp Carousel R530BK microwave won't cook unless light pressure is kept on the door button.

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

Lock faults

test this steps and fix it. God bless you

  1. Open leverCheck your microwave lever to determine if it is damaged. If it is broken, simply replace the lever to get your microwave door fully functional again.
  2. Door springResponsible for keeping downward pressure on the door hook, the microwave door spring can begin to malfunction. If this part is broken and prevents you from opening your microwave door, replacement is necessary.
  3. Door latchOne reason your microwave door may not open properly is a broken door latch. Located inside the microwave, the door latch manipulates the door hook to keep the door closed for safety and top performance. If broken, the door could become stuck in the locked position.
  4. Door hookIf your microwave door will not release properly, the door hook could be damaged. Located inside the door, the door hook is made of plastic and prone to breakage with extended use or age. As this part is unable to be repaired, the only option is to replace it.
  5. Button or button springIf the microwave door will not open, it could be an internal failure of the button or button spring. If it is determined that either of these parts is the source, both are replaceable and it is recommended that they be installed at the same time.
  6. Handle actuatorIf the microwave door will not open the plastic handle actuator could be broken. Connected between the door button and the door latch assembly, this plastic part could become damaged and brittle over time, which makes breaking inevitable. If this occurs, replace the handle actuator to get your microwave fully functional again.

Sear's microwave falling apart

If this is and Over the Range micro, the exhaust fan needs to run ANYTIME the cooktop is on. They make things for quantity and not quality, so the plastic has little tolerance for heat. Running the fan, diminishes heat off the front of the unit. Also, the micro MUST be at leat 24" off the cooktop.

Need to replace GE Spacemaker XL1400 door

On most microwavre ovens all you have to do is open the door all the way and lift straight up at the hinges. The door comes right off the hinge pins. In some cases you may have to remove the top louver panel (right above the door). You should NOT have to unmount the oven to complete this. In fact...I would not recommend it.

Is this a simple matter of replacing a door handle? If you need to only replace the door handle, you just lift slightly on the INNER door plastic around the glass and you will be able to access the door handle screws. There are a series of small grooves in the panel that you can use a small screwdriver to gently pry. You should not have to remove the entire panel. Just open it enough directly behind the door handle. Be careful when prying on the plastic. It can break if you're not careful. I hope this helps you.

Over the range Microwave trouble

It is a door switch problem of some sort.  I have two Sharp R-1611 units that do the same thing.  The light and fan come on, but not the heat, thank goodness.

I am going to replace it since the plastic for the case and door is cracked in numerous places.  I have spent several hours researching microwaves online have not a single clue what to replace the Sharp with.  Seems like every vendor has very good units and very bad units.  I guess you just pay your money and take your chances.

Sharp 1611

Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure.


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:


We also have the complete service manual for this model at our site.

Door Removal Sharp Microwave Model R-1611

The door comes off in a very simple way. Now...I'm speaking from the perspective of MOST microwave ovens. All you should have to do is open the door all the way to the left and lift straight up. The door has mounting pins that fit into a couple of hinge pin holes. If your oven is equipped with an upper panel grid, you may have to remove it, so the door will have more clearance. Putting the new door on is just as simple as lining up the pins in the door with the hinge pin holes and setting the door in place. Close the door slowly to make sure the pins are aligned with the holes properly. If not, the door will fall off while attempting to close. Let me know if this is helpful to you.
