Why is my DriSteem Humidifier not heating?
- JJackie BoothAug 13, 2025
If your DriSteem Humidifier isn't heating, it could be due to several reasons. First, check the main line safety switch and fuses, and ensure the unit is receiving the correct supply voltage. Another possible cause is an incorrect or nonexistent control voltage. In this case, try resetting the control transformer circuit breaker and verify that there's 24 VAC control circuit voltage at T-1 and T-2 on the control board. Also, make sure the humidistat is calling for humidity and that it isn't faulty. Finally, check the safety controls, air flow switch, and high humidistat.
