I have an FC 60C3XNiH WOE 9749717 Echelon 9.C series. Currently is not working. Light in panel shows blinking green. Other light shows amber or yellow blinking. Blinks twice and then eventually goes to red blinking and then back to amber or yellow blinking twice again. Have called a repairman but want to know what is likely wrong. Jerry Noonan, Home owner.
