I've been searching various forums, and it seems the part most likely to cause this problem is a faulty door switch. I've tested all three, and they all test good. Top and bottom are NC, and the middle switch is NO. All cycle appropriately when checking with a multimeter. I've removed the entire switch mount to check them, and I also checked them installed to make sure the door was making physically with the switch actuator.

We've also had rare issues with the reheat auto sensing function causing the microwave to go into error, but I'm not sure if it's related to the primary issue.

What else could cause the fan to turn on when the door is opened?

Out of nowhere, my Ninja cp301 (similar to the unit I selected for this post) does not recognize the tea brewing basket. When I place the orange coffee brewing basket in the unit, it works fine.

Steps I’ve taken:

• “Burped” the unit by turning it upside down and lightly striking it with the palm of my hand.
• Cleaned the unit with a paper towel. Removed a lot of buildup from where the hot water drips down into the brew basket.
• Cleaned the tea brew basket and examined it for damage
• Consulted the owner’s manual for troubleshooting tips

Symptoms:

When I place the tea brewing basket in the unit, the machine’s lights do not indicate “Tea”. Pressing start, on any setting, causes 5 beeps and both the Tea and Coffee light indicators flash. (This is also what happens with no brew basket in the machine)

The coffee brew basket works fine. The machine just suddenly stopped recognizing the tea brew basket for no apparent reason. I had just used the machine to make tea about 3 hours before I noticed the failure.

My question:

How does the machine “know” which basket is inserted? There is something about my tea brew basket that isn’t triggering the proper sensors or something. I doubt running the cleaning function will help, but I am trying that next.

I would greatly appreciate any help or advice on how to get things back in order.

Thanks,

Jason

I don't believe the problem is the puncture needles or the top gasket. I have cleaned and checked both of these, many times, and the needles seems to be puncturing normally. I think the problem is the k-cup ITSELF.

I have observed that, in about 2-3 out of every 5 cups, the top rim of the k-cup actually separates... so, the leakage is not coming from the needle hole area. The leakage is coming from the edge of the k-cup. It is as if there is too much pressure INSIDE the k-cup during brewing, which forces the top covering of the k-cup, causing it to separate from the plastic cup.
