How to troubleshoot a SYSTEL SunPower 65 Gas Heater when the fan does not start?
- CCheryl LopezAug 5, 2025
If the SYSTEL Gas Heater fan isn't starting, several factors could be at play. First, ensure that 220Vac is present by checking the electrical installation. A faulty thermostat could also be the culprit; inspect the thermostat and its cable, replacing if necessary. Similarly, a fault in the gas control box might be the cause, so check the control box fuse and replace it if needed. The fan cord or switch could also be defective, so check their voltage and replace them if necessary. Finally, the fan itself might be faulty, necessitating replacement.
