Steps to Troubleshooting Your Espar/Eberspacher Heater

  • Check the power supply – The first step in troubleshooting an Espar/Eberspacher heater is to ensure that it is receiving power. Check the power connections, fuses, and wiring to make sure everything is properly connected and not damaged. If the heater is not receiving power, address the electrical issue before proceeding further.
  • Inspect fuel supply – One of the most common issues with Espar/Eberspacher heaters is fuel-related problems. Verify that the fuel tank has an adequate supply of fuel and that it is clean. Sediment or debris in the fuel can clog the system and prevent proper operation. If necessary, clean or replace the fuel filter to ensure smooth fuel flow.\
  • Air intake and exhaust – A blocked air intake or exhaust can disrupt the heater’s performance. Check for any obstructions, such as debris or ice, and clear them away. Ensure that the air intake and exhaust pipes are properly connected and free from damage.
  • Check for fault codes – Espar/Eberspacher heaters are equipped with fault code systems that provide valuable diagnostic information. Use the manufacturer’s manual to interpret any fault codes displayed on the control unit. Understanding the specific error can help pinpoint the problem and guide you toward a solution.
  • Check the temperature sensor – A faulty temperature sensor can cause inaccurate temperature readings or prevent the heater from operating correctly. Test the sensor’s resistance with a multimeter according to the manufacturer’s specifications. If the sensor is defective, replace it with a new one.
  • Inspect the combustion chamber – The combustion chamber can accumulate carbon deposits over time, reducing its efficiency. Regular cleaning is essential to maintain optimal performance. Follow the manufacturer’s instructions to safely clean the combustion chamber and remove any debris or soot buildup.
  • Check the wiring and connections – Inspect all wiring and connections associated with the Espar/Eberspacher heater. Look for loose or damaged wires, corrosion, or poor connections. Secure any loose connections and replace damaged wires to ensure proper electrical flow.
  • Consult a professional technician – If you have followed the troubleshooting steps mentioned above and are still unable to resolve the issue, it is advisable to consult a professional technician with experience in Espar/Eberspacher heaters. They have the expertise to diagnose complex problems and perform repairs or replacements if necessary.
