I have a dryer that is running but not producing heat. When I run the diagnostics the code that appears is E5b or E56. I have replaced the thermistor by the blower housing. I also have taken out the thermal fuse, the heating coil, and the high limit fuse and brought them to a local appliance parts warehouse who put them on a multimeter and said they were all set. So the only thing I replaced was the thermistor it ran great for A few loads over the next few days like a new dryer. Then all of a sudden it stopped drying and now it starts a cycle normally taking and will start withled timer then after a while the LEDs start chasing each other then the dryer stops and the 3 lights are blinking next to the start button and I have no heat again. So please help me out. I did purchase the heating coils but haven't installed them applywt cause when I originally went to appliance place they said they were old but fine when put multimeter on it. Please any assistance is awesome. The code again is E5b or E56
It is is a frigidaire affinity model number aeq8000fso
Thanks k you
