Is the turntable properly installed and operating properly?
A thumping or rumbling sound may occur in the microwave oven if the turntable is not installed correctly or if the support roller assembly is not operating properly.
The turntable can rotate in either direction to help cook food more evenly. Do not operate the microwave oven without having the turntable in place.
