I am going through a similar problem but with the Rangemaster 55. I bought the oven thermostat - fitted it and then only to find that the problem was with the flame safety valve.

If you have ordered both parts then I guess you'll fit both. It is not so difficult - assuming the parts are duplicates of the originals. You may need some non setting sealant ( specifically) for natural gas pipeline threaded joints.


Tips are obvious - work in a well ventilated room.

Isolate gas supply ( I mean make a positive disconnection - not just close valve)
Remember which screws fit what
Isolate electrical supply
Leave time for gas pipes to disipate residual gas prior to working on them
Leak test your connections before use - (try soapy water on joints and check for bubbles)
No naked flames near

Hope this helps
