rob111 Posted February 15, 2016 Report Share Posted February 15, 2016 My oil furnace will fire up and burn for about 2 to 3 min. it then trips the burner at the furnace. The blower continues to work properly. I have changed the oil filter and the system is bled. If I reset it it does the same thing. Link to comment Share on other sites More sharing options...
Steven Hockstein Posted February 15, 2016 Report Share Posted February 15, 2016 Do you have oil? Link to comment Share on other sites More sharing options...

Les Posted February 16, 2016 Report Share Posted February 16, 2016 Rob, Steven's question is the right place to start. What are you re-setting? If you are pushing the little reset for the electric motor, it is a quick fix. There are a bunch of different styles of oil furnaces, we are assuming yours is a gun type.

Steven Hockstein Posted February 16, 2016 Report Share Posted February 16, 2016 Thanks for the help My answer was not a joke. I have often seen situations where the burner starts and runs for a short time and then shuts off because there was not a proper or adequate oil supply. Very similar to the condition you described. Maybe you have a bad filter and it is blocking the flow. Link to comment Share on other sites More sharing options...
Marc Posted February 16, 2016 Report Share Posted February 16, 2016 Thanks for the help ... Maybe you have a bad filter and it is blocking the flow. Rob said the filter had been changed. Marc Link to comment Share on other sites More sharing options...

Marc That is my point. Maybe the new filter is defective in some way. Maybe the filter was installed improperly and is inhibiting the flow. It seems like the installation of the filter coincided with the burner problems. Link to comment Share on other sites More sharing options...
rob111 Posted February 16, 2016 Author Report Share Posted February 16, 2016 OK, tank has plenty of oil. Filter changed after problem started. Sorry about the smart a-- reply. anyway, appears to be ok now. did some minor cleaning and cleaned up the connections on the igniter and looks like I got it. Now, where do I find replacement parts for a 40 plus year old M. Wards Signature model 55151A oil burning furnace? Anyone know? Going to do some maint. once warm weather kicks in in Va.

Les Posted February 16, 2016 Report Share Posted February 16, 2016 Rob, likely the furnace is a gun type, so parts are pretty generic and available most anywhere. Oil furnaces are pretty basic, but easily screwed up. Change the filters, nozzle, regulate pressure and air - good to go! If you are not comfortable, then just hire a tech from your oil supply company. Link to comment Share on other sites More sharing options...
Garry Sorrells Posted February 16, 2016 Report Share Posted February 16, 2016 -If there is a stack temp sensor ti may be acting up due to soot, contacts,ect. -The photo eye (cad cell) on the ignitor may be the cause. -Cracked insulator on the ignitor electrode rods may be allowing an intermittent arc to occur. - Wiring, loose connection. - Transformer. Parts: Depends what you are looking for. You can get parts for 60 year old burners, you just have to look a little harder sometimes depending on the manufacture. A lot of parts are adaptable with a little modification. Link to comment Share on other sites More sharing options...
Jim Katen Posted February 17, 2016 Report Share Posted February 17, 2016 If you don't have one already, install a flame retention burner. Someone should take a hard look at the combustion chamber to see if it's in good shape or if there are any holes or broken spots. Link to comment Share on other sites More sharing options...
