Three blinking lights is an Ignition Lockout:
 
# Should the main burner fail to light, or flame is not detected during the trial-for-ignition (TFI) period the control will go into lockout and the valve will be turned off immediately.
# Recovery from lockout requires a manual reset by resetting the thermostat or turning off the ON/OFF switch for a minimum period of 5 seconds.
 
So it’s very possible the flame detection sensor isn’t working. You can test that:

Flame
current is the current which passes through the flame sensor to ground. The minimum flame current necessary to keep system from lockout is 0.7 microamperes. To measure flame current, connect DC microammeter to the FC- FC+ terminals as shown in Figure 5. The meter should read 0.7 microamperes or higher when the heater is firing.[/quote]firing.
