Problem:

tO Error Code

Solution:

If you encounter a tO error code, it signifies that the thermistor's resistance is excessively high or there's an open circuit. This issue might arise due to a blocked vent system or a clogged lint filter. For Flex dryers, check both the upper and lower thermistors (delicate dryer & main dryer).

First, clean the vent and lint filter to resolve the issue.

If the error code persists, contact customer service for assistance.

Agent Note -

A thermistor's resistance should be around 10K Ohms at room temperature.
