1. Check the Thermostat:

Make sure your thermostat is set above room temperature.

 

2. Is the Circulator Pump is Running?

Touch the pump to see if it is warm. Should you find that the pump is running and is cool, take a look at the circuit breaker for the boiler.

 

3. Check Motor Temperature:

Is the motor hot? If you find that the motor is too warm to the touch, this is an indication that the problem is likely the run capacitor; the motor or the pump may be locked. It is cool instead, the thermostat or the circulator relay may be the problem.

 

4. Check Temperature/Pressure Gauge:

The temperature/pressure gauge on your boiler should be greater than zero but below the red line (most gauges have this). If you find the temperature and pressure levels are normal, there could be air in the boiler system. This is often times a common problem with older manual air eliminators, specifically. Should this occur, it is an easy fix by replacing a newer automatic float type air eliminator. 

 5. Check Low Temperature/Pressure:

If you find that the air pressure and temperature are lower than normal, double check to make sure the vent damper is open and/or that the inducer fan is operating. Turn off the circuit breaker for the unit, wait a few minutes and then turn it back on if the fan does not appear to be running. If the inducer is not running or if the damper does not open, the problem may lie with the boiler control or aquastat. The boiler aquastat contains a heat-sensing element that is filled. With that, this enables the device to switch on and off automatically and is equipped to take notice when the water temperature in the boiler falls and rises. This is often attached to the supply riser in the boiler or is mounted, with the heat-sensing element placed inside the well of the steam boiler. 

 

6. Check Water Temperature:

If the system control thermostat is set abnormally high, reset it. 

 

7. Check Main/Pilot Burner:

When the vent damper is open and/or when the inducer fan is operating, check to see if the burners ignite. If the pilot does not light, the vent pipe may be obstructed. If the pilot does light but will not remain lit, the flame sensor and/or the pilot assembly may require cleaning, or the thermocouple and/or boiler control may need to be replaced. If the pilot lights and remains lit for several seconds, check the main burners to make sure they light. If those do not, the gas valve and/or the boiler control may need replaced as well. One thing to notes is the safe position may not be activated when the air pressure lever is turned on to the safe position. This switch may need to be replaced. 

 

8. Check for Overheating & Noise:

Have you found that there is poo air circulation in the main circuit? If so, the system may need to be vented. Check for any foreign objects that could cause any abnormal noises, as there is a possibility there could be something obstructing the pipe.
