good morning I request service manual whirlpool wrm 37b, someone has changed the field sensor. Problem: after a while 4 LEDs start to flash, but if I disconnect and reconnect, they stop flashing for a while, change the module power and still the same, someone inform me if the field sensor is 2.7 or 10k another detail does not cut and the frizer reaches -35 degrees Celsius. I already appreciate your collaboration
