SAFETY CONSIDERATIONS
Installing and servicing heating equipment can be hazardous due to
gas and electrical components. Only trained and qualified person-
nel should install, repair, or service heating equipment.
Untrained personnel can perform basic maintenance functions
such as cleaning and replacing air filters. All other operations must
be performed by trained service personnel. When working on
heating equipment, observe precautions in the literature, on tags,
and on labels attached to or shipped with the unit and other safety
precautions that may apply.
Follow all safety codes. In the United States, refer to the National
Fuel Gas Code (NFGC) NFPA No. 54-1992/ANSI Z223.1-1992.
In Canada, refer to the current edition of the National Standard of

* For casing widths larger than 14-1/4 in., 0 clearance may be used.
† 18 in. front clearance required for alcove.
‡ Clearance shown is for the outlet end. The inlet end must maintain 6 in.
clearance from flue to combustible materials when using single-wall vent.
** Indicates supply or return sides when furnace is in the horizontal position.
NOTES:
1. Provide 30-in. front clearance for servicing. An open door in front of the
furnace can meet this requirement.
2. A minimum clearance of 3 in. must be provided in front of the furnace for
combustion air and proper operation.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

    • T
      theresa86Aug 18, 2025
      If the limit or flame roll-out switch is open in your Carrier Furnace, check for several potential issues: - Ensure there's an adequate supply of combustion air, especially for the FRS switch. - Inspect the filter and duct system for any dirt or restrictions. - Verify the blower wheel is securely in place. - Check the switch and its connections for defects. - Examine the blower motor and capacitor for any failures.

    How to fix ignition-proving fault in Carrier Furnace?
    • L
      Lori MillerAug 22, 2025
      If your Carrier Furnace displays an ignition-proving fault, consider the following checks: - Inspect the flame-proving sensor for oxide buildup and clean it gently with fine sandpaper. - Ensure the flame-proving microamps are at least 0.5. - Verify proper control ground continuity. - Confirm the flame-proving sensor is ungrounded. - Ensure smooth flame carryover and ignition. - Check that the manual valve(s) are not in the OFF position.

    What causes low-heat pressure, draft safeguard, or aux-limit switch not to close or reopen in Carrier 58TMA?
    • A
      Andrew WilsonAug 25, 2025
      If the low-heat pressure, draft safeguard, or auxiliary limit switch in your Carrier Furnace did not close or reopened, check the following: - Ensure proper vent sizing and condensate pitch, especially with side-wall vents. - Verify low inducer voltage (115v). - Inspect the blower motor and capacitor. - Check for a defective inducer motor. - Examine the pressure switch for defects. - Consider excessive wind conditions. - Look for a restricted vent. - Ensure an adequate combustion air supply. - Check for disconnected or obstructed pressure tubing.
