Buying home, need to replace old double oven with cooktop unit. Trips 40A break

existing unit is oven with cooktop and attached upper second oven. when all is turned on, it trips the 40A breaker. inspector suggests 50A breaker. I want to replace unit with a conventional oven/cooktop/microwave unit. Will i still need to replace the breaker?
home built in 1983. No idea what size wire goes to this unit. it's about 50' from the breaker box.
Thank you.

Inspector suggests upsizing to a 50A breaker but has no idea of the size of wire feeding the appliance.

That's criminal. Home inspectors are usually just worthless and stupid.... this one is also dangerous.

The key information information is missing from your post:
  • Full load amps of old appliance.
  • Full load amps of new appliance.
  • Size wires to appliance location.
  • Do you have 2-conductor cable +ground or 3-conductor cable +ground or continuous metal conduit with at least 3 wires?
inspector suggests 50A breaker
I'll bet he is not an electrical inspector. Unless you have #6 you can not increase the breaker size.
No idea what size wire goes to this unit.
Look in the breaker box. Buy a foot of #10, #8, #6 THHN/THWN wire at the hardware store, strip a couple inches of insulation, and compare to the stripped wire in the breaker.
