What to do if Saturn Furnace burner ignites but shuts off quickly?
- E
  Edward JacksonAug 17, 2025
  If the Saturn Furnace burner ignites but does not stay running and shuts off on reset within 15 seconds, consider these potential causes: * There might be a fuel delivery problem; follow the procedures listed in the next problem. * The cad cell could be dirty; clean and check its condition along with the cad cell wires. * Cad cell wires might be loose; ensure the yellow wires are properly connected at the 'F' terminals on the oil primary control. * The cad cell or its wires could be damaged; replace them if necessary. * The primary control might not be receiving the correct ohm signal from the cad cell; disconnect the yellow wires from the 'F' terminals, start the burner, and check the ohm reading from the cad cell.

How to fix a Saturn Furnace pump that won't prime but the motor is running?
- Y
  Yolanda WernerAug 20, 2025
  If the Saturn Furnace pump won’t prime but the pump motor is running, several issues could be the cause. First, there might be a leak in the suction line, so ensure it is installed properly and all fittings are airtight. Second, make sure the pump head is filled with oil before starting the pump. Third, the pump gears could be dry, so fill the oil line and prime the pump. Fourth, a damaged pump seal could be the problem; if there is oil at the pump shaft, replace the pump or the seal. Fifth, check if the ball valve is closed and open it. Finally, the canister or check valve might be dirty, so refer to Section 9 to clean them. If none of these steps work, the pump may be damaged or worn out and require replacement.

Saturn Furnace burner ignites then shuts off later - what's wrong?
- P
  Patrick RamirezAug 27, 2025
  If the Saturn Furnace burner ignites and then shuts off on reset sometime later during the day or night, consider these potential issues: * There might be air in the fuel supply; prime the pump. * The primary control may not be receiving the correct ohm signal from the cad cell; check for proper ohm signal. * There could be insufficient air pressure; follow the instructions in Section 5 to adjust the air regulator for proper air pressure. * The heater block might be cold; do not shut off power to the furnace overnight to prevent the heater block from cooling down. * The electrodes could be fouled; follow the instructions in Section 8 to check for proper draft overfire and clean the electrodes and retention head.

Why does my Saturn Furnace burner shut off periodically after running properly?
- K
  Kimberly DayAug 30, 2025
  If the Saturn Furnace burner ignites and runs properly but shuts off on reset periodically, it could be due to: * Air in the suction oil line due to leaks at the fittings; follow the procedures in Section 5 to vacuum test the pump and properly seal the suction line fittings to eliminate air leaks. * Air trapped in a high point in the pressure oil line; bleed the air out of the pressure oil line.

  April RiosSep 3, 2025
  If the Saturn Furnace pump won’t prime and the pump motor is not running, check the following: First, ensure there is power on the pump circuit from the burner, start the burner and adjust the air pressure regulator to 15 PSI. Second, the pump motor may have shut off on thermal overload; wait for the motor to cool down, as the thermal switch will automatically reset.

Why won't the fan motor in my Saturn Furnace run?
- T
  Tammy ValdezSep 10, 2025
  If the fan motor will not run in your Saturn Furnace, there are several possible reasons: * The fan motor may not be wired correctly; check the fan motor wiring. * The blower/fan switch may be defective; replace the blower/fan switch. * The fan motor may have overheated and shut down on thermal reset; wait for the motor to cool down, as the thermal switch will automatically reset.
