I've attached the portion of the manual which shows how to lock & unlock this model.

If that doesn't work, unplug the oven for one minute, plug it back in aga9in, then try again.

If it still doesn;t work, then your keypad has failed, and they are no longer available for these model, so the oven would have to be retired.

Good luck.

No! I'am afraid not, the problem is in the keypad control board, the whole assembly must be replaced, the part alone will cost around $100.00 or more depending on make and model.

I would expect that you have a shorting membrane keypad.

The original part number for the plastic frame with keypad was FPNLCB074MRK0 but it is no longer available.

The oven will have to be retired.

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.

On some models, the keypad would have to be replaced. On others, the connectors can be cleaned to fix this.

First check all door switches are properly working. If they are ok , the defect may be in the key pad. You need to replace the key pad.

Sharp-R9h84b Pad Numbers


I'm sorry to tell you, but your keypad is failing and the supplies of membrane keypads for these models were exhausted years ago and they're no longer available.

As great as these old workhorses were, once they become unusable or unreliable, they will have to be retired.

Please don't kill the messenger! *grin*

Sharp Carousel Convection Oven. Model R-9H54.touch pad


It depends on what you mean by "a problem with the touch pad assembly".

If some or all keys do not respond, you would probably need a new keypad, but the key units for all Sharp R-9H-series models have been unavailable for a few years now.

These units did indeed last a long time.

Sorry I can't bring better news.
