Review on 🔍 Coleman Furnace Replacement Pressure: 9371DO HS 0031 - Find the Perfect Fit! by Will Kern

Need a (more expensive) dual port switch. The initial error was a 3 blink error. When the unit arrived the other side (2 flashing DTCs) had also failed. R&R was easy, used the new tube from the kit and left the spare tube on the bottom.
