This unit is 8 years old. There is a knocking or tapping sound coming from the bottom - intermittently. Maybe once every 10 mins 4-5 knocks. It sounds like the Qc fan to me. Is it difficult to pull and replace? Looks like it's just behind the grill.
ANSWER Hello Richard,
You will have to disassemble the duct system behind crispers to get to this. It can be done but pay close attention to how the unit comes apart. You may also want to check to see if it is the fan making the noise or the duct assembly that is on the left side of this assembly.
