Quadra Fire control box flashes 3 times

Suspect Thermocouple is the issue, am I right?

Only if the light is amber. Do you have the clear plastic control box, or the old grey one?

newer box, amber light

Quad 1200 Thermocouple Testing

THE THERMOCOUPLE IS MADE UP OF TWO DISSIMILAR METALS THAT WHEN JOINED TOGETHER PRODUCE A
SMALL AMOUNT OF ELECTRICITY WHEN HEAT IS APPLIED. THE HOTTER THE FIRE THE HIGHER THE VOLTAGE
THAT IS PRODUCED. THIS THERMOCOUPLE WILL TOP OUT AT AROUND 30 MILLIVOLTS (DC) WHILE THE STOVE IS
BURNING ON HIGH. THE FUNCTION OF THE THERMOCOUPLE IS TO SENSE THE TEMPERATURE IN THE FIREPOT. IF
THE THERMOCOUPLE IS FRACTURED, IT WILL NOT PRODUCE VOLTAGE.
NOTE: BE SURE TO SET THE METER TO MILLIVOLTS (DC)
1) ATTACH A DIGITAL VOLT METER TO THE TWO THERMOCOUPLE WIRES ON THE JUNCTION BOX.
2) APPLY HEAT TO THE THERMOCOUPLE TIP IN THE FIREPOT.
IF THE THERMOCOUPLE STARTS PRODUCING VOLTAGE: CHECK TERMINAL CONNECTIONS ON THE JUNCTION
BOX OR REPLACE THE CONTROL BOX.
IF NO VOLTAGE FROM THE THERMOCOUPLE: REPLACE THE THERMOCOUPLE

New thermocouple installed, problem solved, burnt 6 tons so far this year and still heating, when is spring again?
