Residential Fuel Pump Failure, No Longer a Mystery

Not long ago, I was contacted by a Pennsylvania independent heating oil dealer struggling with multiple service call-backs due to seized residential heating oil fuel pumps. The owner of the heating oil company described his frustration with this customer’s “No Heat” calls and wondered what his customer must be thinking?
When he got to the home, he found the heater primary control had gone off on safety causing the heater to shut down. Pulling back the transformer, he noted the pump coupler, squirrel cage and fuel pump were tight but was able to free them up on the burner. After reassembly and pressing the reset button atop the primary control, the heater started and ran through a normal cycle. He presented an invoice for the service call; the customer was happy to have heat. Problem solved, or so he thought!
 
About a week later, the same customer called and had no heat. Upon arrival, he again found the heater off on safety. The fuel pump coupler and squirrel cage were tight, and the fuel pump was bound. At this point, he replaced the fuel pump with a new one straight out of a box and ran the heater through a normal cycle. For good measure, he cycled the heater on and off a couple more times. Because he had to replace the pump, he did the right thing, charging the customer for parts only.
Within two weeks’ time, the same customer called again with no heat. Again, the heater was found off on safety. Again, the pump coupler, squirrel cage, and fuel pump were bound up. What is going on here? Could it be a bad pump? He pulled the new pump installed last service call and replaced it with another new one. He assured the customer the issue was solved and there was no charge. When he left the customer, the heater was running and producing heat. Wait a minute…the fourth call a week later!

At his wits end, the dealer called his HVAC supply house. Unknown to the heating oil dealer, his service calls and pump problems were actually suspected to be related to the stability and storage quality of locally available heating fuel in customer tanks. I had encountered this same pump sticking scenario with other Pennsylvania dealers and learned this issue is wider spread than the Northeast. As a matter of fact, one of my associates at AFS had previously worked with NORA staff members and a dealer in Washington State with the same type of pump failures.
