FIXED EWED65HIW0 Electrolux runs but no heat E64

EWED65HIW0

I am getting an E64 error code on my dryer. This indicates a heating element issue.

I tested the Element, High Limit Thermostat and Fuse... they all tested OK but each has now been replaced. Still receive the error message. New parts test with continuity as expected.

I tested the inlet thermistor and was not getting resistance, this was replaced but still no heat. New piece resistance tests with 57k ohms

I have checked the voltage at the outlet and to the terminal. 240 as expected. I have flipped the breaker just in case.

I have tried to check the control board but that is a little tougher. When not running, the heater relays test as open, when running in a heat cycle they test as closed. From what I can tell this is to be expected for proper functioning. That is as far as I have tested.

There is an outlet thermistor - I did check that last night and was not getting good results... seemed weird that both would be out but I would not get a thermistor code so I figured I was testing it wrong.

There is a fuse on the exhaust as well (forget what it is called) that tested with continuity.

I am down to thinking it could be the control board, outlet thermistor or wiring. Any thoughts on something I may be missing or good ways to test from here?

*I have also checked for things like lint blockages, fan blades and such... all seem OK.

Ok,

E64=Heater Open Circuit
Heating element or wiring defective.
Check heater coils and connections for open circuits. Replace heater and/or wiring and retest.

There is an outlet thermistor - I did check that last night and was not getting good results... seemed weird that both would be out but I would not get a thermistor code so I figured I was testing it wrong.

Check resistance of Outlet Control Thermistor, Resistance should be between 4.9K Ohm and 6.2K Ohm at room temperature (68-77° F or 20-25° C).

Replace Outlet Control Thermistor if bad.

Here's the outlet control thermistor for your model:
Thermistor 134711300


Let us know what you find.

The heating element is new - tested continuity and that tests OK.

Tested the outlet thermistor and that tests at 5.5k

new control board came, installed. problem persists.

ok.. I think I got it. There was a wire that came loose from the motor. Broke off at the connector is more like it. After spending a few hours trying to get the connector blade of the terminal, I finally got it... now to find a replacement one. Not sure if M1 or M2 but one of the thicker ones.

That was it - posting in case others run into similar things. I (tried) to follow all the "normal" heating elements and each tested good but being an old dryer and unsure of my skills, I sided with replacing them but kept hitting walls. "Wiring" in the book seemed pretty vague but found it by trying to follow the circuit all the way through to the end and actually feeling along every wire - past what I thought would be likely heating components. I probably would have seen the wire earlier had I taken the drum off at some point, but I thought it was easier to leave it on - this was not visible with it on from the front or back.
There are probably some control panel tests that could have shown this but everything seemed to be checking out there (again... limited skills).
In the end, the part I needed was $0.39 - pays to buy from a company that will let you return parts though!

Excellent, glad you found it was just a wire that came loose from the motor heat switch problem.

Thanks for the update!
