Longtime reader, first time poster...great forum.... Was troubleshooting my heater for flow issues (turned out to be the filter itself). Had the covers off when a leak sprung from the drain plug in the heater. Forgot to shut down the electricity; not sure what happened, but heard a sound akin to someone stepping on a plastic water bottle. My assumption is that water shorted one of the adjacent connections. I replaced the fuse on the board as well as the fireman's switch, and, generally, still no display on the board/panel, which after following the troubleshooting steps, led me to order a replacement control board. However, as I was playing around, I noticed that if I cranked down (applied pressure, primarily perpendicular to the pins) on the two connectors that include the 24v supply, the card would light up and the heater would engage. It would start up the blower motor and try to fire, then shut down, although if I laid off the connector at all, it would immediately die. Knowing enough about cicruit card assembly to be dangerous, did I inadvertantly burn out some of the inner-layer circuitry wtih overvoltage/current? Otherwise, can't logically figure out why the board works as clearly the micorprocessor is ok. Just don't want to install the new board and figure out it was something else. Appreciate any perspective or experience.
