Folks,
About a year and a half ago I replaced an aging Lochinvar Fin-Tube model with a new Weil-McClain Evergreen Series, Model 220. The swap was done in early spring of 2016. December of that same year (9 months or so later) the unit began sporadic lock-outs due to Blower Fault usually during the Pre-Purge cycle.
I contacted WM and after a bit of back and forth (check this, test that), they agreed the blower was to blame, and authorized a warranty repair on the blower and controller.
Today, 11 months later, the problem resurfaced. The new blower motor is about 11 months old and it is faulting and causing lock-out during Pre-Purge.
If I stand at the boiler and command the different blower speeds, the return signal is in-line with desired results. This is a sporadic issue - and since the blower replacement last December, I'm thinking it can't possibly have anything to do with the main control board, or the wiring to said board. The vent/intake piping is all full 4" terminated at a WM branded plate outside. The manual says that a blower fault during startup indicates that either the blower didn't required speed for ignition, or didn't return to full stop when 0% signal was commanded. If the damn thing is just finicky, is this something that a field rep could "reprogram"? We're at 7,550ft altitude, and the blower has been set to 7500ft.
I'm going to call WM in the morning again - but each time I replace this thing I'm paying shipping through the local distributor, and because this boiler servers our business ( a motel ), I am going to need the replacement part asap... like yesterday.
Lastly, we just built a new 4-room building in April of this year and put one of these boilers in that building. If this new boiler also starts having blower faults at the 9-12month mark, we're going to have a real problem.
Any help or insight is appreciated.
Thank you,
Pete
