Gas Oven Control Switch jammed - Stoves 700GDO

[Mike]

Our gas oven - a Stoves model 700GDO has two controls, the one which operates the Grill and upper oven is very stiff, when the oven is on you require a pair of pliers to turn it off.

Any suggestions whats caused this fault ?

Anyone have a user manual fof Stoves or alink

it looks like you need to dismantle the valve - so perhaps left to a specialist.

I imagine the original lubricant has gone "gummy"

carry it - probably by Dupont, not much required or at least less than the previous idiot used on a gas fire.
