The furnace is about 15 years old. It tries to turn on and then it stops. It has fast alternating flashing lights:
Lights mean the following:
IMPROPER MAIN GROUND OR LINE VOLTAGE BELOW 75 VOLTS, OR BROKEN IGNITOR, OR OPEN IGNITOR CIRCUIT.
Also being winter should I be looking into getting electric or other heaters to provide warmth for the home?
