Why is my PolyScience WB05A11B Laboratory Equipment not heating?

  Patricia LopezAug 4, 2025
  There are several reasons why your PolyScience Laboratory Equipment might not be heating: * The set point might be lower than the bath temperature. In this case, check the set point temperature and increase it as needed. * The bath temperature might be above the High Limit temperature. Verify that the High Limit temperature is higher than the current set point temperature and adjust it if necessary. * The liquid level in the bath might be too low. Check that the liquid level is at least 2 inches (5.08 cm) above the bottom of the tank, and add fluid if required.

  Bryan MooreAug 18, 2025
  Insufficient heating in your PolyScience Laboratory Equipment can occur due to: * Improper line voltage. Ensure that the line voltage meets the equipment's specifications. * A recent change in set point or heat load. Allow sufficient time for the bath temperature to stabilize after making changes. * The bath cover not being in place. Make sure the bath cover is properly positioned.
