troubleshoot aquastat no circ
Trying to see why my aquastat 8124 is not turning on circulator. Aquastat was just replaced 2 years ago because of the relay. I don't see any burns on it anywhere. Solder is solid throughout. Checking for 24v at the thermostat terminals of the controller and i get nothing. Thought the head valves were bad, but I tested the switches on both and they seem fine. 24 runs through 2 thermostats to valves and properly opens them. Noticed if I pushed on system board with volt meter leads, I get 24v and the circ comes on. Really sounds like board, but I'm not convinced. Why don't I get 24v at the terminals unless the relay fires? Ran 24v directly to thermostat terminals on AS and still nothing.
