What to do if the limit or flame roll-out switch is open in Carrier 58TMA?
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?
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?
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.
Why does the secondary voltage fuse keep opening in my Carrier 58TMA Furnace?
If the secondary voltage fuse is open in your Carrier Furnace, check for a short-circuit in the secondary voltage (24V) wiring.
What causes high-heat pressure switch or relay not to close or reopen in Carrier 58TMA?
If the high-heat pressure switch or relay in your Carrier Furnace did not close or reopened, the control relay may be defective, so check it.
