Issue: A/C Fan runs when mode set to furnace Models Impacted: Dometic Penguin II equipped Information: The on-board thermostat communicates with the Dometic Penguin II A/C unit and the A/C unit then communicates with the Furnace. When the mode is set to Furnace the A/C fan should not run if set to AUTO. If the fan speed is set to LOW or HIGH, this will cause the A/C unit fan to run with the Furnace as a means to distribute the inside air flow. If you are experiencing this issue, please ensure that the fan speed on the A/C is set to AUTO. Resolution: Normal Operation *If the A/C fan runs when set to Auto and mode is set to Furnace, then another issue exists and the Dometic A/C unit should be inspected by a Dometic certified technician.
