Gas problems

[Biker chic]

I changed my gas bottle and the hob burners did not burn all the way around then all was ok. Oven worked fine as did truma heater, boiler and fridge. I’ve now switched to another new bottle but fridge will not stay lit unless I sit for ages holding the button in (10mins last time and if I ease the pressure slightly the flame dips and I push again and it’s lit) (old 2004 Swift Sundance with Dometic 3 way fridge) Now last trip out no hot water as boiler will not stay lit, it clicks on and about 3-4 seconds later clicks out and red light come on. So far the fire is fine as is the oven. I have tried having all appliances on at once but water heater will still not stay lit. I am hoping the is an easy fix! Thanks fo any advice

Sounds to me like a faulty regulator ?
Caveat ; I'm no gas expert

I would look at the regulator first it's the least expensive and easiest to do

Yes regulator may be faulty pressure too low. Easy change

Thanks everyone. It’s back into its winter storage so it’ll be in my to do list and I’m hopeful this will fix it, as you say the least expensive!!

When you go back to your van, you'll need to check the steel gas pipe size (8mm or 10mm normally) and the orientation (side entry, bottom entry) then give Autogas 2000 a ring.
