Hitachi Microwave Oven MRO-W1X - Reason for Discount

Purchased at Yamada Outlet in October 2020.
The purchase price was ¥52,000.

Since the end of last year, the microwave has been stopping with an error code during operation.

I investigated and replaced a part that seemed to be the cause, and the symptom improved. However, the same error occurred again last month.

I suspect the issue is a poor connection with the replaced part, but I have already purchased a new one, so I am listing this for sale.

I will also include the spare part I bought, shown in image 14.
The same part has been installed in the relevant location.

Since it was in a location easily accessible from the outside, I assumed the manufacturer also recognizes this part as prone to degradation and replacement.

I am not from a science or engineering background, but I can recommend this to those who can replace parts themselves. However, I do not recommend purchasing it if you are not able to do so.

The oven function, such as for making bread, was working normally.
