Problem with Weil-Mclain boiler
My WM boiler is acting up. Have had no heat for the last 2 days. I have it shut off for now. When I turn it on, the power light comes on, then the TSTAT/Circ light, and then that's it. I'm thinking the control module is bad because no lights flash to tell me there's any kind of error or bad sensor, and the flame light doesn't flash after the allotted 15 seconds to detect flame from the pilot. BUT - could the electric pilot ignitor be bad? It's a CG model, and control module is 11365-605
