[Resolved]  IFB Industries — ifb washing machine amc

I purchased ifb washing machine in year 2009. It worked well for first 7.5 years. Since then it started giving problems.

My machine is in amc. Today we found that the door lock got damaged.

The technician inspected machine and told us 2 things:
1. He will try to find a lock and if he fails to get a lock then we need to buy entire door.

2. Technician predicted the root cause of problem might be fluctuation in power supply/earthing, so he suggested to buy a ifb controller.

My question is :
1. Amc includes replacement of metal parts then we should get a door as part of amc because door is a metal part.

2. Since controller is an external part, can we use controller of any other company?

3. What is the official price of ifb controller and door?
