If your Snugger Heater is not starting and is not displaying any error codes, try the following: * Turn the heater off and then back on. Ensure the heat button (with the 3 arrows) is pressed, not the ventilation mode button. * Check all electrical connections for damage or corrosion. * Inspect the fuses to ensure they are not burned out. * Verify the voltage going to the heater is within the correct range. * Remove power to the heater for at least 5 minutes by removing the main fuse at the battery, then reinstall and test. * Test with a new controller. * Install a new electronic control unit and test.
