Sharp R-9H66 Microwave Oven will stop while in convection mode after about 5 min. The heating element heats and is still red but the fan goes off. We can immediately start it again but it will stop again after about 5 min. This happens on pre-heat or after it is heated. Microwave still works fine. Appreciate any suggestions.

SOURCE: Sharp Covection Oven/Microwave stops after 1min on any setting

This 59-second stop failure is due to a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper is a door inside that opens or closes depending on cooking mode. If the controller thinks that the door is not in the right position, it will shut down the cook cycle.

See the attached sample photo.

SOURCE: Sharp R-930 convection/microwave works fine in all

For that problem I would check the sensors. If the sensorblock is faulty, it will think it is hot when cold etc.
Hope this helps.

My Sharp microwave convection oven (R-967M / R96STM) cuts out during convection pre-heating and cooking, It appears it stops heating after 1 min. If the START button is pressed again the oven starts...
Also the fact it is a convection oven could mean the oven temperature sensor is not picking up the oven temp. it is not telling the machine it is there by the board seeing its resistance, the unit will shut off as a safety feature. The oven sees temperature by reading the value of a temperature dependent resistor. As the temperature changes so does the value of the component ( oven temp sensor) that way the unit determines the temperature inside the unit. Sometimes those sensors will break since they are in the area with the heat and moisture, they get old and break.

For a 1995 Sharp Carousel Convection Microwave oven Model # R-9H66 it has on display screen ''LOCK'' and will not allow any function, is there a solution? The light inside works when the door is opened...
Check the user book for the unlock code. This could be the child lock mode.

If one of the safety switches are defective, or if there is a sensed power supply fault, the uPC will put the oven in the lock mode for safety reasons.

Ge convection micro combination has a problem with convection fan . fan runs for about 5 seconds, rattles, then stops. heat element gets red hot but little heat inide oven. replace fan motor or maybe more?...
I would say the convection fan blade is loose on the shaft.

If this is the case, it would try to run, but no cooling would take place, so the heat from the heating element would get very high but it would not be distributed through the oven.

The thermistor would then detect the extra high heat and stop it, I assume.

You may be able to use super glue or JB Weld to fix the blade on the shaft, as long as they are clean and dry and it is allowed to set overnight.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

Accessing these components for testing and possible replacement will require you to remove the oven from the wall and take off the outer cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.
