Common Troubleshooting Tips for the Lennox SLP98 Furnace

 

  1. Check the air filter: A dirty or clogged air filter can cause a wide range of issues, including reduced airflow, decreased efficiency, and even system shutdowns. Check the air filter regularly and replace it if necessary.
  2. Check the thermostat: If the furnace isn’t working properly, the thermostat may be the culprit. Check the thermostat settings and make sure it is set to “heat” mode. If it’s battery-powered, replace the batteries.
  3. Check the gas supply: Make sure that the gas supply to the furnace is turned on and that the gas valve is open. If the gas supply is off or the valve is closed, the furnace won’t function.
  4. Check the igniter: If the furnace isn’t turning on, the igniter may be faulty. Inspect the igniter for cracks or damage and replace it if necessary.
