24FEB2025 Jason Brown Arrived for call back on recent repair. Spoke with Mrs Mary Henry about her systems performance. She explained that the first time I was out it stopped heating, and then came back, and then this morning she woke up and the home was cold. Cycled system at thermostat and watched ignition process. Found gas valve not opening. Checked voltage to gas valve and found board providing 28v. Rewired gas valve tested pressure switch, switch closing at -1.4 iwc, drains are clear. Cycled gas valve several times, cycled furnace many times. Ran furnace for 15 min checked heat rise, verified blower motor amps and run cap. System is heating properly at this time. Discussed findings with homeowner, we decided to hold off on replacing the gas valve at this time.
