I have a Weber Summit built-in (natural gas) grill. For the past few years, the grill will not get hot upon lighting it after it rains. For example, if it rained yesterday, today the grill lights but won't get hot. I can't cook food on it. The burners are generally dimmer and the gas pressure seems much lower. I've tried many things to try to overcome this situation:
- Let the grill warm up for a long period of time (an hour).
- Clean the burner tubes
- disassemble the manifold / knob assembly to blow out any potentially-clogged orifices. I used pressurized air and also WD 40. I had called Weber at one point and they said that spider webs can form and they expand with humidity.
- I turn off the local gas shut-off and then purge the gas from the lines inside the grill by turning the knobs. I then turn the gas back on.
I'm struggling to understand which gas components are susceptible to rain / dampness. At this point, I really feel like it is not the grill itself, but the gas supply or perhaps the gas regulator.
I'd be grateful to anyone who can help me diagnose this problem.
