little update

You know how sometimes you discover you were really close to solving something, except you needed to know one little tiny detail to get it to work? But you actually knew the detail and didnt see how it connects to what you were trying to do?

For the future, if you have an oil furnace, the blower has a little photo sensor to tell if the spark lit the flame.

If the blower sees the light of a flame, it continues to feed oil, activating the pump.

Good so far.

If you shine a flashlight at the sensor, it tricks the blower in the same way a flame does.

Knew that.

I just had to shine a flash light at the sensor while bleeding the oil pump. Eventually it’ll suck out all the air and oil will start coming out into the little canister like a soda bottle you had at the bleeder valve.

Once just oil and no air or frothy oil comes out, close the valve and your done. Take the flash light off the sensor, replace the cover you removed to get to it, and your enjoy hot water in your place.

If you needed this, i probably saved you some money and time getting a service guy to do the same thing. Now that i wrote it down, I wont forget for next time.

Just be careful and if you dont feel confident or willing to do it yourself, hire a pro.
