4.Disconnect pressure switch tubes.

5.Disconnect vent pipe from inducer housing outlet by loosening clamp.

6.Disconnect drain tube from inducer housing. (See Fig. 6 - 14.)

7.Remove inducer housing assembly by removing 4 bolts attaching assembly to cell panel.

8.Flush inside of collector box with water until discharge from condensate trap is clean and runs freely.

NOTE: Ensure that drain tube disconnected from inducer housing is higher than collector box opening or water will flow out tube.

9.Inspect inside area of collector box for any pieces of foreign materials and remove if present.

!CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in furnace component damage.

DO NOT use wire brush or other sharp object to inspect or dislodge materials in secondary heat exchangers as failure of the secondary heat exchanger may occur. Flush with water only.

11.Refer to furnace wiring diagram and connect wires to inducer motor and pressure switch or connectors.

12.Reconnect pressure tubes to pressure switch. See diagram on main furnace door for proper location of tubes. Be sure tubes are not kinked. (See Fig. 6 - 14.)

13.Turn on gas and electrical supplies to furnace.

14.Check furnace operation through 2 complete heat operating cycles. Check area below inducer housing, vent pipe, and condensate trap to ensure no condensate leaks occur. If leaks are found, correct problem.

!WARNING

FIRE OR EXPLOSION HAZARD

Failure to follow the warnings could result in personal injury, death, or property damage.

Never test for gas leaks with an open flame. Use a commercially available soap solution made specifically for the detection of leaks to check all connections.

15.Check for gas leaks.

16.Replace main furnace door.

Procedure 6 — Servicing Hot Surface Igniter

10. Reassemble inducer assembly by reversing items 5 through 7. Tighten the vent coupling screw(s) to 15 in.-lb. of torque.

NOTE: If gasket between inducer housing and collector box is damaged in any way, it must be replaced. (See Fig. 16.)

The igniter does NOT require annual inspection. Check igniter resistance before removal.

1.Turn off gas and electrical supplies to furnace.

2.Remove main furnace door.

3.Disconnect igniter wire connection.

58HDX specifications

The Carrier 58HDX is a high-efficiency gas furnace that embodies advanced technology and reliable performance aimed at providing superior home comfort. As part of Carrier’s Infinity series, the 58HDX is engineered for exceptional energy efficiency, convincing homeowners that they are making a sound investment in their heating solutions.

One of the standout features of the Carrier 58HDX is its variable-speed blower motor. This technology allows the furnace to adjust its operation based on the heating needs of the home, providing steady, consistent heating while also optimizing energy use. This results in quieter operation and improved comfort levels since it reduces temperature swings commonly experienced with single-speed systems.

The 58HDX is designed with a two-stage heating system that enhances efficiency and comfort. It operates on a lower heat setting for most conditions, only ramping up to high heat during extremely cold weather to deliver consistent warmth without significant energy waste. This flexibility not only contributes to energy savings but also extends the lifespan of the unit.

Equipped with a highly efficient heat exchanger, the Carrier 58HDX boasts an impressive Annual Fuel Utilization Efficiency (AFUE) rating of up to 98%. This rating means that nearly all the fuel consumed is converted into heat for the home, making it one of the most efficient furnaces available on the market. This efficiency translates directly to lower utility bills and a reduced carbon footprint.

Furthermore, the 58HDX also includes advanced diagnostics and is compatible with Carrier’s Infinity® System Control. This integration allows users to monitor and control their home’s heating system remotely, ensuring comfort at their fingertips. With Wi-Fi enabled technology, homeowners can adjust settings, receive alerts for maintenance, and track energy usage.

The unit is also designed with increased reliability in mind. Features such as a durable cabinet, high-quality insulation, and a corrosion-resistant heat exchanger ensure long-lasting operation, while a quiet combustion process and integrated flame sensor improve safety and performance.

In summary, the Carrier 58HDX gas furnace brings together innovation, efficiency, and dependability. With its variable-speed blower, two-stage heating capability, high AFUE rating, and smart technology integration, it stands out as an ideal choice for homeowners looking to enhance comfort while managing energy costs.
