The furnace does function for quite a while, but it does not stay running. When it stops running, an led light goes on in the control box (you can see the led through a hole in the control box cover. On the control box cover it instructs: " If led is on remove power momentarily..If the led stays lit, replace the control unit, if it goes out consult the service manual."
The led is going out when the power is interupted. The label intructs to consult the service manual. Is there a way to consult a manual?
