Here is Atwood's troubleshooting tips for their 1511 heater like what you have for if the unit does not heat:
Check circuit breaker is on
Control cable may be unplugged between outside unit and inside fascia
Check power supply to vehicle
Ensure mode has been switched to heat (check
Green LED)
Thermostat set point must be above room temperature
Based on your LED being red and not green it sounds like yours isn't set to heat yet.
