My Frigidaire Gallery refrigerator showing HI temp.and with code5Y and EF, what does it mean?
An EF code is indicative of an Evaporator Fan Circuit Failure. Can it be stopped by ice or frost? Absolutely. Press the freezer up button and the freezer down button simultaneously for 6-8 seconds and you will enter a test mode. Every time you press the fresh food button after entering the test you will advance to the next test. They are not in numerical order. Go to test 26 (The defrost circuit test) and it will show CL for closed or OP for open. If it shows OP you have a defrost issue. If CL there is no defrost problem. Next go to test 15 - keeping in mind they ( the tests are Not in numerical order). When you get to 15 press the main power on/off button. The 1st time you press it the display will show LO and the fan should be on low speed. The next time you press the power button it will show HI, and the fan should be on high. It is a twelve vdc fan motor wire colors red, yellow, brown, and blue. They originate at the j6a and j4a connectors. If the fan does not come on in the test the check will be made at the control. There should always be 12vdc between brown and red, and there should be 9 - 12 vdc between brown and yellow in the test. The blue wire is a tach wire and feeds info back to the lower control which is located behind the kick plate underneath the unit. EX factory service 22 years currently an instructor.
