Hey all my Carver Cascade Rapid II is not firing up
im getting a red light next to the flame icon on the control panel.
The book suggests an air lock & to repeatedly turn it on which I have been doing all weekend.

Any ideas of what to do..................................

Ignitor board or gas valve failure.

I guess you need to get into the works to see if theres a spark and check for gas at the burner.

Swap LPG cylinders sometimes works, especially if tank is low.

Assume you've not done what we did one weekend and left the cover on :doh::doh:
Tried that switched to a full cylinder & no joy, also tried it again when we got home & still no joy.

Silly question I know, but have you removed the flue guard?
I haven't touched anything on it, would this be the plastic cover outside

Do you have a window open over the exhaust as that will stop it working as it has an inhibitor switch.

If you guys mean a separate cover that goes over the vent I do not have one, the only cover is the actual vent, I can go & unscrew it.

Try the gas regulator. We had the same symptoms in spain. Fridge and hob still working but red light when trying to get hot water. Replaced regulator and bingo!
Thanks to @seanoo

Have you had it lit before? Simple things like gas isolator etc. Can you hear it trying to light?

Update: 26/10/15

we are on EHU in Norfolk & been here well over 24hrs & tested the gas today & it worked 1st time.

since 2006 ( I think ! )
If we do not use the gas option on ours for a week or so it rarely lights first time..
Always have to wait for the error code, turn it off and turn it back on..
Tried all sorts and then spoke to others with the same vintage set up as we have.. They get the same !

Has it been serviced Lately?. Stuff like Spider webs etc; can cause misfires and the like. Our fridge for example. stopped working on gas, Cause was rust from the vent had dropped onto the Burner. Intermittent faults can be temporarily "Cured" by having driven the van and shifted "debris".?

BTW, The genny on the r-v stopped working, Cause was a Clump of debris left behind by a "mudspider" nest!! (not found in the UK though)
