How to Determine If Your Furnace’s Oil Pump Is Broken

Your furnace’s oil pump is responsible for circulating oil to the burner. It is also responsible for maintaining the oil pressure in the lines. If your furnace’s oil pump is working improperly, it can cause a decrease in heating efficiency and an increase in your heating bills. Below, we’ve listed a few things you should look for to determine if your furnace’s oil pump is broken.

The Furnace Isn’t Starting Up

The oil pump is responsible for supplying oil to the burner. If the oil pump is broken, the burner will not receive any oil, and the furnace will not start up. Although the furnace’s failure to start could be caused by several issues like a clogged filter or a tripped breaker, if you’ve ruled those issues out, it’s likely that the oil pump is to blame.

The Burner Is Making Strange Noises

If the oil pump is broken, it can cause the burner to make strange noises. The motor that powers the oil pump can become noisy if it is not getting enough oil. This can cause a rattling sound that you may be able to hear when the furnace is running. In addition, the lack of oil can cause the burner to run dry. This can result in a banging noise as the burner tries to ignite and will need to be repaired.

The noise is similar to an engine running low on oil — a ticking sound. If you hear this, the pump isn’t supplying enough oil to keep the burner lubricated, and the metal-on-metal contact is causing the noise.

The Oil Pump Does Not Turn On

The oil pump is powered by a motor. If the motor is not working, the oil pump will not turn on. You can check to see if the motor is working by listening for a humming noise when the furnace is running. If you do not hear a humming noise, the motor is not working and will need to be replaced.

The Oil Pressure Is Low

If the oil pressure is low, it can cause the furnace to run less efficiently. The oil pressure can be checked by using a pressure gauge, and it should be between 10 and 20 psi. This process is usually performed by a professional. If the pressure is below 10 psi, it means that the oil pump is not working properly and needs to be replaced.

The Furnace Is Running but Not Heating

If the oil pump is broken, it can cause the furnace to run but not heat. The oil pump circulates oil to the burner and is responsible for maintaining the oil pressure in the lines. If the oil pump is broken, the burner will not receive enough oil and cannot generate enough heat to warm your home.

A broken oil pump can cause your furnace to run without providing heat, so if you notice this happening, the oil pump is probably at fault.

The Furnace Is Shutting Off Unexpectedly

If the oil pump is not working, it can cause the furnace to shut off unexpectedly. This is because the oil pump maintains the oil pressure in the lines. If the oil pump is broken, the pressure in the lines will drop, and the furnace will shut off.

A broken oil pump can cause your furnace to shut down due to low pressure, so if this happens, have the oil pump checked as soon as possible.

The Oil Pump Is Overheating

The oil pump circulates oil to the burner for combustion. If the oil pump is broken, the oil will not circulate properly, and this will cause the oil pump to overheat. If the oil pump overheats, it can cause a fire. An overheating oil pump is very serious, so if you notice this, shut off the furnace and call a professional immediately.

The Oil Pump Is Leaking

If the oil pump is broken and the oil is not circulating properly, that might cause the oil pump to leak. The leak can be either oil or coolant. If you notice a leak, shut off the furnace and contact your technician.

If you notice any of these problems with your furnace, you should get your heating equipment checked out by a professional.
