How to Install Glass Cooking Tray 00487763 in a Bosch Microwave

Quick answer: Unplug the microwave, lift out the old tray and roller ring, and wipe the cavity floor and coupler hub. Reseat the roller ring, lower glass tray 00487763 so its center recess drops over the coupler tabs, and rotate it by hand to confirm it turns smoothly before a short test with a cup of water.

The glass cooking tray 00487763 is the round turntable plate for Bosch built-in microwaves such as the HBL5750UC02, HBL5750UC09, HBL5720UC02 and HBL5760UC06. Food sits on it, and a small motor under the cavity floor spins it through a plastic coupler so the microwaves heat evenly instead of leaving cold spots. Trays crack from thermal shock, chip when a heavy dish lands on the edge, or simply shatter after years of use, and the oven should not be run without one because splatter and drips then fall onto the coupler and the cavity floor.

Installation is about as easy as an appliance repair gets: no fasteners and no wiring. What matters is cleaning the surfaces the tray rides on, getting the center recess to sit correctly on the coupler, and handling a heavy piece of tempered glass without knocking it against the door frame. Our fitment data lists 43 compatible Bosch models. Trays vary in diameter and hub shape between series, so match the part number to your model rather than measuring a broken tray.

⚠️ Safety First
  • Unplug the microwave or switch off its breaker before reaching into the cavity, especially on a built-in unit shared with an oven.
  • Let the cavity cool completely; a tray that has just been used can be hot enough to burn and is more fragile while hot.
  • Sweep up every fragment of a shattered tray with gloves on and vacuum the cavity, because glass shards can wedge in the roller ring track.
  • Carry the new tray with both hands and set it down on a towel, never on a bare hard counter edge.

Tools and Parts You Need

  • Glass cooking tray 00487763
  • Soft cloth and warm soapy water
  • Microfiber towel for drying
  • Small brush for the coupler and roller ring track
  • Flashlight to inspect the cavity floor
  • Microwave-safe cup for the test run

Step-by-Step Installation

  1. Disconnect power and cool down Unplug the unit or turn off its breaker and wait until the cavity is cool to the touch. Open the door fully so both hands can reach the tray.
  2. Remove the old tray and ring Lift the old tray straight up off the coupler. If it is broken, gather the pieces carefully. Then lift out the roller ring that sits in the circular track beneath it.
  3. Clean the cavity floor Wipe the floor with warm soapy water and dry it. Brush crumbs and grease out of the roller ring track and inspect the small wheels on the ring; if they are cracked or flattened they will make the new tray wobble.
  4. Check the coupler Look at the plastic coupler in the center of the floor. Its tabs should stand up straight and it should spin by hand with slight resistance from the motor. Wipe it clean so the tray hub seats fully.
  5. Replace the roller ring Set the roller ring back in its track with the wheels facing down and give it a spin to confirm it rolls freely all the way around.
  6. Seat the new tray Hold glass tray 00487763 level and lower it so the molded recess on its underside drops over the coupler tabs. Turn the tray a few degrees until it settles onto the tabs and stops rocking.
  7. Spin test by hand Rotate the tray slowly by hand. It should turn the coupler with it, ride evenly on the roller ring and stay centered with no scraping against the cavity walls.
  8. Run a short heating test Restore power, place a cup of water on the tray and run the microwave for about a minute. Watch through the window to confirm the tray rotates smoothly and quietly.

Fit Checks Before You Call the Job Done

  • The center recess of the tray is fully engaged on the coupler tabs and the tray does not lift or shift when nudged.
  • The tray sits level on the roller ring with an even gap to the cavity walls all the way around.
  • The tray rotates smoothly with the motor and does not stall, click or wobble.
  • No fragments of the old tray remain in the roller ring track or under the coupler.
  • The door closes freely without the tray edge touching the door frame.

Common Mistakes to Avoid

Running the oven without a tray The coupler and floor take direct splatter and heat, and food heats unevenly. Wait for the replacement rather than cooking without it.

Buying by diameter alone Two Bosch trays can share a diameter yet have different hub recesses. A mismatch will spin unevenly or slip off the coupler. Match the part number to your model.

Setting the tray on a dirty coupler Dried food under the hub keeps the tray from seating, which causes wobble and eventually chips the glass at the center.

Forgetting the roller ring Without the ring the tray tilts and rides on the coupler alone, straining the motor and rocking during use.

Troubleshooting After Installation

Tray does not rotate Lift the tray and try turning the coupler by hand. If it will not turn, the turntable motor or coupler is the problem, not the tray. If the coupler turns, reseat the tray so the recess engages the tabs.

Tray wobbles or clicks while turning Check for debris in the roller ring track, cracked ring wheels or a coupler tab that is bent. Clean or replace the ring and reseat the tray.

Tray scrapes the cavity wall The tray is off center because the hub is not on the coupler. Lift it, center the recess over the tabs and lower it straight down.

Care Tips After the Repair

  • Wash the tray with warm soapy water or on the top rack of a dishwasher after it has cooled; avoid abrasive pads that scratch the glass.
  • Wipe spills off the roller ring track weekly so the wheels do not gum up.
  • Do not lift the tray by one edge with a heavy dish on it; remove the dish first.

Frequently Asked Questions

Can I use a tray from another microwave if it is the same size?

It is not recommended. The hub recess and roller ring height are matched to the Bosch cavity, and a tray from a different brand may sit high, wobble or not engage the coupler.

Is the glass tray dishwasher safe?

The tempered glass tolerates normal dishwasher cycles once it has cooled. Place it on the top rack away from heavy items, and check your owner's manual for any model-specific advice.

Why did my tray crack with no impact?

Thermal shock is the usual cause, such as a cold dish placed on a hot tray, or a hairline chip that finally spread. Let the tray cool between uses and retire any tray with a chip.
