Maintenance methods and precautions for temperature controllers

1. General maintenance methods for temperature controllers
Use dry cloth or soft brush to clean the surface and internal components of the controller regularly to prevent dust from affecting heat dissipation or poor contact. Avoid using detergents containing corrosive chemicals during wiping, and turn off the power when cleaning. Laboratory equipment needs to clean the filter element and heat dissipation channel regularly to prevent dust accumulation. The temperature control relay needs to check whether the contacts are oxidized or burned, and the wiring terminals need to be tightened to avoid short circuits.
The installation location of the machine should be away from humid, high temperature or vibration areas, and keep it ventilated and dry. Grease pollution should be avoided in industrial environments, and household equipment should be kept away from heat sources.

2. Targeted maintenance measures
Regularly calibrate the accuracy of temperature sensors (such as thermocouples and thermal resistors) and compare the difference between actual temperature and displayed value. Check whether the metal sheet in the mechanical thermostat is sensitive to deformation and whether the contacts are oxidized. Check whether the circuit board of the electronic thermostat is damp and whether the relay operates normally; update the software to fix system vulnerabilities.

3. Precautions during maintenance
Be sure to turn off the power before product maintenance, and industrial equipment must be cooled to a safe temperature. If you encounter a complex fault (such as circuit board damage, program error), you need to contact a professional to handle it. It is recommended that household equipment be inspected every six months, and industrial equipment be maintained monthly or quarterly according to the frequency of use.
