Fridge not staying lit

[Benhudson]

Hi we have a 2010 Autotrail frontier navajo with a Thetford 3way fridge model N97.
Last wk we where away and our fridge would not lit on gas, it kept trying to light then going out.
I made some enquiries and replaced the spark electrode that also doubles as a flame failure device.
The fridge is still not staying lit, the flame lights immediately the spark is produced, but then after about 1 minute the flame goes out.
Any advice please?

check all the wiring connectors for corrosion check the burner is earthed properly its either lack off gas or the flame rectification is dropping out

Hi Thanks for the reply.
I will do what you suggested, but tried it again last night and it worked fine.
