Downloaded Trouble shoot guide from Frigidaire, E47 error code, test PTC(Wax Motor) in Door latch assembly. Removing this found 945ohms, not 1500 or short as expected in guide. Opened assembly and observed design and function. Pressed contacts closer together for Aux Switch (wax motor activated) and reinstalled the assembly. Cleared E47 code from front panel and ran spin cycle. It worked, loaded up backed up laundry and got through three loads before E47 came back.
Found replacment assembly online, lowest is $39. Can't source Wax Motor via Frigidaire. Found Wax Motor for Maytag, p/n 12002535, for $8 online at dryerpartsonline.com. Part looks the same, but different color. Risky. Part is also at RepairClinic.com for $12, p/n 1063620
Going to call local dealer during day, see what replacment cost is without waiting for shipment. Will inquire about Wax Motor for Maytag. Compare in store.
