Furnace diagnostice




The technician took too long to do his job. I was charged for two hours of service when in fact the job can be done in about an hour. I had Supreme Air did my initial installation of my Trane system in October 2009 and they did not register the product. Therefore, I was not able to get the 10 years part warranty.

Upon arrival I found thermostat for package system off. Customer let me in but left soon after. Went to unit and found status LED Light on. Found condensate pump full but getting correct voltage to pump. Engaged float and motor barely runs. Replaced condensate pump from truck stock. Was unable to get approval from customer. Because they are SA customers I replaced so they have heat in the main portion of house. Tested system and checked amp draw and delta air temps. Unit operating normally. Also lowered flow rate of water to humidifier because it was pretty high. Did not collect. Son came home when I was leaving and informed me that she may be at church.

I replaced the filters for each unit. I operated each unit on second and auxiliary heat stages. Temperature rise normal in second stage and auxiliary heat strips energize as intended. I pressurized the ground loop and set the flow rates to match the printed data. I checked the electrical wiring and electrical, all are within specification. Customer inquired about humidifier pad replacement. I told customer this was not part of the service but could be done after I service the units. While operating the package unit I turned the humidistat to call for humidity. The valve opened but did not turn off even after the blower went off. The wiring to the humidifier is not correct and the wiring needs to be run from the accessory relay from the board so that it can only energize if the heat or blower are operating. Both units are operating normal.

Upon arrival I found all thermostats calling for heat but geo system in standby. Checked voltage at zone panel and found 24v on all correct terminals for thermostat side. Found no voltage on equipment side. Suspected either Zone Panel fault or equipment safety cutting out power. Shook condensate pump and it started pumping and Geo system started running. Opened up pump and found no debri or blockages, actually very clean. Found it was installed in May. I tested pump 8 times after and working perfectly every time. Unit operating normal.

I replaced the gas valve, tested for leaks and for normal furnace operation. Unit operating normal. Customer paid remaining balance of $259.95 which shows as a credit until the office applies it to the balance from the repair code.

I replaced the filter for unit #1. I operated both units on 2nd and auxiliary heat stages. I reset the pressure drops to 3.5 for each unit and pressurized the ground loop to 65 psi. I checked the electrical wiring and electrical systems, all are within specification except for the capacitor for unit #1. It has just dropped below specification and therefore should be replaced. Customer will replace in the spring. I prepared an estimate. Otherwise the units are in good working order and are operating normal.

Found unit with the door metal to it . Had to pull door off with a flat head screw driver , also burn marks in the intake pvc pipe. The unit was off on a pressure switch and I found that there is a restriction in the heat exchanger . Also looked at the heat exchanger and it is badly rusted. Unit is from 1995 and has problems before with the flame rolling out . I turned system off by the power and gas because I believe that the heat exchanger is breach . By the coloration, rust and burn marks inside of unit . Costumer also told me they had the fire department out before for the flames rolling out and catching the unit on fire. That’s another indication that the heat exchanger is compromised. Recommend replacing system but gave estimate for inducer motor and heat exchanger . Unit is in very poor condition.

The igniter would glow and the gas valve open but voltage to the valve was dropping. I could hear the pressure switch clicking internally and used a series of test to confirm that there was adequate pressure in the burner box and that the pressure switch was faulty. Installed a universal pressure switch and set it for the same rating as the one I removed. Tested the operation of the furnace 10 times to make sure there were no other issues. The furnace ignited and operated without a problem each of those times. Unit is operating normal.

Upon arrival customer informed me that the furnace had started working. Colin identified a gas valve issue during a previous service. I found the manifold pressure is 3.0 iwc and cannot be adjusted because the adjustment cap is seized in place. I measured 24 volts at the gas valve each time I tested it. It also started each time. There is a lot of rust inside the furnace. The inducer motor pulls adequate pressure 1.95-2.05 iwc and has normal operating amps but it is loud at start up, which is a concern. Customer also informed that the unit was flashing fault code 2, which is failure for gas to light. I’m recommending replacing the valve as well. I made an estimate for this repair. Customer approved the repair and signed up for a service agreement for 2 systems and paid the service agreement in full for a year and $200 toward the gas valve replacement. Once the part is ordered and picked up a technician will return to replace.
