Water furnace 7 series lower level equipment is experiencing ABC control board intermittent failure. Upon arrival today the color touch screen communicating thermostat was displaying Aurora web link communication errors, the web link itself had one solid green light only with no Wi-Fi connectivity or communication lights illuminated, and the ABC board would not auto disconnect AWL in Aurora configuration setup. It would only display no communications and could not be removed from the list. At the same time the equipment was set to 70° but reading 70.8 and still running on heating speed compressor 4 with blower speed 4. Aid tool fault recall shows 1 x E56 (DROVRCUR) and 1 x E99 system power reset Recommend replacing ABC control board under parts and equipment warranty. NVV060A 180301873 Seth will contact water furnace to confirm warranty, order parts, and prepare estimate *All systems are online including the lower level Aurora web link after high voltage power reboot The upper

Upon arrival inspected furnace and found no major concerns, went to thermostat and cycled heat, system attempted to start up and when gas valve sequenced, the control board started buzzing really loud and it didn’t cycle the valve. Once blower came on buzzing continued and wouldn’t go away, restart cycle and gas valve worked 2nd try but still had buzzing noises and it shut off, then blower continued again. Started tapping on control board in common relay locations and buzzing faded quickly. Restarted system and unit came on properly and started heating. Control board is faulty and should be replaced but the whole furnace is growing close to the point of replacement. Unit has substantially taken on rust damage from air coil drain line and multiple electrical parts have been damaged. Recommend replacement of furnace only ac is newer 17” coil

Upon arrival discovered loose wiring in thermostat, tightened connections and test ran heat pump, heat pump putting 3° delta T out, outdoor air 15° will have to inspect refrigerant circuit once wether is above at least 30°. Inspected heat strip circuit and each circuit kicked on individually after going through all timers. Refrigerant pressure at 6psi

Furnace locked out on a 31 code. High Pressure switch open. Furnace has water damage underneath the drain trap. Found gasket leaking. Pulled and flushed trap. Tested pressure switches: high pressure switch rated 0.75", actual pressure readings averaged 1.6" Voltage drop across the contacts during operation is high, measured 0.5V drop. Low pressure switch rated 0.3", actual pressure readings stayed above .4" voltage drop across the contacts is 0.03V High pressure switch has weak contacts which is causing the furnace to not work properly. **Need to replace pressure switch kit under the factory parts warranty. Labor is not covered by the warranty.** Furnace began throwing 33 code, tripping high temperature limit. Furnace has a Honeywell 16x25x4 media cabinet. Builder incorrectly said it is OK to use 16x25x1 filters. 1" thick filters are more restrictive on airflow, which causes the furnace to overheat. We only recommend using Honeywell brand 16x25x4 MERV 8 filters. Gas pressur

Upon arrival inspected humidifier and discovered panel was decently built up with calcium deposits. After inspecting filter discovered it was in upside down, as well as the stopper for the plastic supply line is broken and allows humidifier supply line to go beyond the bracket and dump water outside of the panel. Quote replacement housing and perform brief inspection on furnace to verify no possible callbacks, discovered decently rusty burners, informed homeowners and offered to upgrade burners with the panel replacement. As well as add a 3” condensation trap for the intake pipe to preserve new burners as much as possible

Per Chuck, furnace was showing code 1 during no heat. Code one on furnace control means ignition retries exceeded(3). Upon arrival, furnace was not running, thermostat was set to heat at 70 ad was reading 70, and no codes on the furnace. Tested all components that take part in the ignition process. Tested inducer motor, Amp draw and induced draft within spec. Tested ignitor at 51ohms, and is getting proper 120v. Gas valve operated properly and gas pressure is within spec. Flame sensor is clean and was working properly at 2.5microamps. Thernostat called for heating and was satisfied twice for testing. Blower motor operated within Amp draw specifications. Air filter in good condition. Unable to pinpoint a problem with the furnace at this time. Failure could possibly be control board do to problems being intermitten with no rhyme or reason to be happening. System is properly operating in heat at this time.

Water furnace Envision NDV072 system is short cycling on the water flow service LED lock out light indicating freezing conditions at the FP1 sensor measuring the refrigerant temperature discharging the coax heat exchanger. Initial testing found 0 PSI on the ground loops. After recharging ground loops with house water pressure to 65 PSI the system continued to short cycle on water flow. Deeper investigation and refrigerant pressure testing shows the system is moderately low on refrigerant and will run on first stage heating but drops below the threshold and locks out on fp1 in high stage heat pump heating Electronic testing before recharges did not find any leaks at this time. Visible dark spots running down the air coil are possible indications of refrigerant oil leaking through the copper tubing Recharge refrigerant today and inject new calgon leak stop with ultraviolet dye. 88 oz new R410A Recommend follow up refrigerant leak search for the ultraviolet dye and running refrigerant p
