Why is my Broan GSHH3K Fan not operating as per the selected mode?
If your Broan Fan unit isn't operating as expected, ensure the main switch is set to the “Normal/Remote” position. Also, verify the wall control wiring is correctly connected.
What to do if Broan GSHH3K does not start at Low or High position?
If your Broan Fan isn't starting at either the Low or High position, take these steps: * Check the breaker or fuse in the main distribution panel or GFI outlet. * Confirm there is 120V at the electrical outlet. * Ensure the unit's main switch is correctly set to the Normal or Boost position. * If a wall control (ACCGSC1 or 40425) is connected, disconnect the control wire from the unit, then ensure the unit's main switch is properly set to the Normal/Remote or Boost position. * Inspect the fuse on the electronic board; if it's blown, replace it with the same type.
Why Broan GSHH3K does not run at Low speed, but runs at High?
If your Broan Fan only runs at High speed and not Low speed, and if you're using a wall control (ACCGSC1 or 40425), disconnect the control wire from the unit. If the unit then runs at Normal speed, inspect the control wiring and wall control connections.
