Why does my Weil-McLain WGO 4 rapidly cycle on and off?
Rapid cycling in your Weil-McLain Boiler can occur for several reasons. It may be due to the thermostat being installed in a location affected by drafts or heat, in which case, relocate the thermostat to an inner wall away from heat sources or cool drafts. Another cause could be an incorrectly adjusted heat anticipator in the thermostat; adjust the heat anticipator to match the current draw, referring to the boiler wiring diagram. Finally, an incorrect limit setting might be the issue. A qualified service technician can increase the limit setting to decrease cycling, up to a maximum setting of 220° F.
What to do if Weil-McLain WGO 4 requires frequent makeup water additions?
