The flashing Ready light tells us that the Sensors may be bad. The next option is the control panel. It interacts with the sensors. Check the thermostat with a good ohm meter. The two thermistors (High Limit and thermostat) should be very close to the same Ohm's with the circulation pump running and the heater off.
