What does the E1 code on Aroma rice cookers actually point to?

[Thomas Martinez]

Saw the E1 code come up a few times when people is troubleshooting Aroma rice cookers and decided to post what I've read about it. The E1 code indicate an open circuit in the temperature sensor. Essentaly the cooker cannot read any signal from the sensor so it cannot start up to heat the pots.
The suggestion is typically to open the machine up and inspect the sensor connection. Most of the time it isnt the sensor itself that is causing the issue, but instead one of the wires that is coming loose. If the sensor and connections check out, then you would have to replace the sensor itself.
Do the temperature sensor on these rice cookers use NTC thermistors as I seem to remember reading? Is it easy to find replacement?

yeah they're just standard NTC thermistors, usually 100k. I pulled one out of a dead ARC-150 last year and matched it to a generic off amazon for like 4 bucks. Nothing proprietary about it.
