I have a propane wall furnace that keeps shutting down randomly with error 11 code. I’ve had four different repair technicians out. Unit has been cleaned, flame rods replaced, igniter replaced, gas pressure adjusted, burner cleaned, etc. Problem still persists. Technicians have spoken to Rinnai with video chats. Today technician was told he needs to blow it out with an air compressor which no other Rinnai representative said to do. We all know unit is a lemon, but they won’t replace. Keep finding new things to try on my dime. I will never buy another Rinnai product. They do not stand behind their product, and representatives tell technician different things. Totally disgusted. How many times do I need to pay a technician to come out? Rinnai doesn’t care.
