Thermostat Unresponsive to Touch

Last updated: October 28, 2026

This article helps you if the screen of Mysa for Electric Baseboard Heaters is on, but Mysa does not respond to its controls. Do the steps in this order.

For Mysa for Mini-Splits, refer to the Mysa for Mini-Splits Device Hardware Guide.

1. Remove the protective film

Make sure that you removed all of the protective film from the front plate. Film on the front plate can stop Mysa from sensing your touch.

2. Do a hard reboot

Turn off the circuit breaker. Wait 30 seconds. Then turn on the circuit breaker.

3. V1 only: Examine the ground wire

A loose ground wire can cause problems with the touch controls on V1. Gen3, V2 and Lite do not have a ground lead. Do not do this step on Gen3, V2 or Lite.

  1. Before you remove Mysa from the wall, turn off the circuit breaker. Make sure that the power is off.

  2. Make sure that the ground wire is tightly attached to the ground screw in the gang box.

  3. Put Mysa back on the wall. Then turn on the circuit breaker.

4. Remove the front plate and look for the green LED

To remove the front plate, loosen the screw on the bottom of the front plate. Then slide the front plate off Mysa.

  1. Remove the front plate. Look for the green LED.

  2. If you do not see the green LED: Turn off the circuit breaker. Make sure that the line wire from the breaker is tightly connected to the Mysa L1 lead.

  3. If you see the green LED: Mysa receives power. Keep the front plate off for 3 to 5 minutes. Then put the front plate back on Mysa.

When you put the front plate back, be careful. Do not bend the pins on the front plate. Put the front plate on Mysa. It glides into place. Tighten the screw on the bottom of the front plate. Do not overtighten the screw.
