Was wondering if someone could please help me out on this; I have a Raypak Natural Gas Heater (auto start) bought and installed in 2013 and just turned it on to heat the pool and it's reading "Rollout SW Open". I have read elsewhere on this site someone having a similar problem and have established that the rollout switch is open and I have found it. It does not have a button to restart it, I am wondering if there is anything I can do before having to call for service? I have cut the power and turned it back on; turned off the gas shut-off and turned it back on, and opened the panel and cleaned all the debris I could with a rag. Any help would be much appreciated.
