Whirlpool India — Whirlpool fridge sealed parts not working after 1 year

I bought this fridge around 2 years back but it is not working now. Servicr technician asking Rs 4000 for the sealed parts. What guarantee does Whirlpool gives on sealed parts?. So now I have to keep shedding out 5k to 10k on this 50k fridge.
This is really the worst brand experience to me.
