Ben for Model Number Frigidaire LGHN2844MFO Error code "sy ef". Evaporator fan runs when I put 12V across Red and Brown wires while giving Yellow Wire 12V as well. Continuity confirmed for all wires from fan plug on harness to plugs at control board. With all connected, have confirmed 12 V across R/W and B/W at control board. B/W seems to be holding steady 5.4V. Y/W sits at around 0.5V and then occasionally rises to 1.5-2.0V and settles back to 0.5V. Fan does not turn and "sy ef" code returns. Is this likely control board or the fan motor (ie, should fan spin with 2V on Y/W or should board be putting out higher voltage on that terminal?) Thanks!
Answer Ben, For this issue the control board would likely be the cause for this issue. Read More... Answered by AppliancePartsPros.com | Wednesday, December 5, 2018
