I did post on here about our fire not working on gas, several people replied and I tried several of the replies but with no success. Today took it to repair shop and they showed me that the base plate had cracked, not rust as was suggested.I did ask whether it could be repaired but they said no. By lifting the plate the gas came on right away. The cost of replacing is very high, the part alone cost £75 plu all the bits and bobs.
