Hi. We had a Girard tankless hot water heater installed a month ago. Last week while the trailer (2012 Rockwood Ultralite 2907SS) was in for service, they replaced the magnet switch stating it was not working correctly. The hot water worked fine last night, but this morning we cannot get any hot water. The fan is turning on, but the burner is not igniting. Gerard tech support is closed until Monday and we are on the road heading to Disney with 4 kids. REALLY need hot water (despise bath houses
). I have read and read all info and we are still stuck. LED diagnostic light not lighting up, propane full and working to stove, heater, Etc. Unable to view flame. Would appreciate any help...thanks! Signed...very frustrated Mom
