Evcon model EZ-2025 unit model UGAB075BUG. When thermostat is turned on in heat mode the unit functions fine up to blower coming on. it's all heated up and the unit get 4 red blinking lights: High Aux. or split limit switch open. Then it shuts down. What is the next step. I have replaced entire control units before but this doesn't call for that. if more information is needed please contact me at [email protected]. Thank you, warren.
