I replaced three wire safety pilot for Bryant boiler. Installed new pilot tubing and fittings. Safety switch closed after 53 seconds of lighting. Boiler operated for about 15 minutes and new pilot assembly failed!! Had new pilot assembly picked up delivered. Replaced again and tested operation. Safety switched closed after 20 seconds. Cycled pilot on and off. Working OK.

Picked up keys from 707 N 2nd St. Unit C: Goodman 2123: I found electric furnace with bad transformer. I tested controls and wiring for shorts and found none. Also found evaporator coil very dirty. System running without a filter. I tested for shorted and grounded controls and wiring. Found none. I replaced transformer with fuse. Check control circuit amps for cooling and heating modes: 0.45 A. I clean evaporator. Replaced air filter. Unit D: checked to see if heat is operational. Found heat was working and set at 58. Dropped off keys at 4564 Chouteau.

Cleaned & checked gas furnace. Inspected heat exchanger & flue venting. cleaned burners & flame sensor. Checked voltage & amp draw of motors. Test capacitor. Replaced air filter. Blower: 3.8/4.7A . Inducer:0.09/0.21A . Gas pressure: 1.9/3.6 inches water column. Found basement pressure negative (-.006 inches water column) due to leaks in return-air ducting. Suggestions: return ducting air leaks can be sealed with caulk and tape. Keep basement door open for make-up air to keep pressures balanced. Set fan to “auto“ position when in cooling mode for proper humidity control. Recommend whole house humidifier installation: $716. 15% PMA discount applies.

Found condensate pump float safety tripped. Pump not able to pump water through frozen line that goes to the outside. Humidifier was installed last year and connected to this existing condensate pump system. Condensate pump system works for warm weather only. No charges today. Suggestions: run new condensate discharge line over to drain stack where washing machine drains.
