Review on 🔧 Enhanced Diesel Air Parking Heater Switch Replacement by Michael Dixon

bought 2 pieces. 1 to replace my old and spare. I've found that the LEDs that illuminate the display will eventually give you up if you leave the heater on for a long period of time (e.g. 6 months straight). off-season AND record the pump and fan settings in your current unit to carry over to the new one. 1688 is the code to access the settings so you can copy them.
