Convotherm gas combi oven dilemmas
New here and stumped. I run maintenance at an oil site and in the kitchen there is a newer convotherm oven thats doing my head in. It is less than 18 months old and has started throwing a gas fault.. this fault however is mentioned once in the manual and it’s suggestion is to open the gas valve and fire unit… why didn’t I think of that? Lol
The problem is, I’m never around when its happening repeatedly. I finally managed to get the fault once. So I turned off the unit. Switched the gas valve OFF and tried again. Same fault would you believe it! Only it took 5 minutes longer than the initial attempt with gas valve open.. 🤔
So I pull the panel off to investigate.. all looks good. Try start up procedure.. success. Again and again and again. Success. Making me think its a combustion air issue. So I put the panel back on. Start up procedure.. SUCCESS!!!! WHAT THE F$^K. This is my first time with this unit and I’m lost. I cant trouble shoot the unit when it’s working. Anyone have any ideas?
Its a convotherm c4et 20.20 gs on propane supply.
Fault code is E05.3.1.0. NO GAS..
There is gas. Arrrrgghh
