Common Failures
Temperature controllers may experience unresponsive keypad buttons, particularly the up and down keys used to adjust the set temperature. In some cases, keypad rust has been identified as a contributing factor during evaluation.
Repair Approach
When keypad issues are identified, the repair process may include cleaning affected components. If the case or front cover shows wear, sealant may be applied to restore structural integrity when replacement parts are not available. All repairs are subject to evaluation and quotation before work begins.
Testing & Quality Assurance
Following repair, controllers are tested and calibrated. Testing includes verification of RTD and temperature scale settings. Units may undergo extended testing with load to confirm proper operation. Each repair is reviewed by qualified personnel to ensure it meets CSL quality standards.
