Questions & Answers


Can I replace a 7505b1500 with a 7505p1515

Asked by Bubba February 19, 2021

The answer would depend on the appliance to which this burner is attached. If you look under the header "Info and Guides" on the Home Depot product listing page you will find a PDF of the specification sheet. That same sheet covers both controls. It the differences are not relevant to or aren't used on your devise than yes. However if they are critical than no. Sorry I can't give you a definitive answer. But as I said it depends the logic designed into the devises control strategy.

what does flashing light mean recycle

Asked by sal February 1, 2019

It means your burner control tripped out because there could be a clog or smudge in the line. You could also have a bad ignition. You should hire a professional. Sometimes it need a maintenance cleaning too. Press the button to re ignite the system and hopefully it holds

How do you adjust the sensitivity of this? Serviceman replaced my old relay type model with this ...

Asked by Montclair August 14, 2017

As a continuation from the last question. There is no sensitivity adjustment on a relay. The switch is either open or closed. If the relay is going into reset mode than the cad cell is most likely not see light. The unit could certainly be bad but If its brand new I would assume its doing its job and you have a combustion issue that a qualified burner tech needs to chase down. It could be a bad cad cell. bad fuel,, bad oil pump or a number of things. The tech needs to isolate the individual components in operation cascade and figure out which one is not performing.
