Problem with Electrolux 3 Way Fridge

[rls106]

Hi, I run fridge on gas. Last night gas ran out and I heard igniter clicking. I changed gas bottle for a new one but no clicking sound from fridge. I cleaned connectors on rear of switch and tried again but still no clicking. After about three hours clicking started again. I tried to start fridge but ignition failed and clicking sound stopped.
I vaguely remember a post previously where somebody had similar problem and eventually clicking returned and fridge started.
Does anybody know what problem can be?

Very likely dirt in the jet ,you could put an airline into it ,I used my tyre pump hose it worked again. Then later bought a new burner that comes with jet in the connector thread ,working perfect now
