Why Trane Technologies Air Conditioner will not heat or cool, but the fan switch operates?
- S
  Steven ThomasSep 3, 2025
  If your Trane Technologies Air Conditioner's fan switch works, but it's not heating or cooling, it could be due to: * A defective Zone Sensor Module (ZSM). Refer to the Zone Sensor Module (ZSM) Test Procedures. * A problem in the ZSM wiring. Disconnect the ZSM wiring at the RTRM and test the wires using the Zone Sensor Test Procedures to locate any wiring problems.

Why Trane Technologies Voyager 3 Air Conditioner minimum position is at zero, cannot be adjusted?
- J
  Jason Herrera MDSep 19, 2025
  If the minimum position on your Trane Technologies Air Conditioner is at zero and cannot be adjusted, it's possible that the remote Minimum position potentiometer has failed. With the main power off, check the resistance between terminals on J8 at the Customer Connection Module by rotating the remote minimum position potentiometer knob. Resistance should be 50 to 200 Ohms.

Why Trane Technologies Air Conditioner will not heat (YC’s only): GV does not energize, CFM runs, igniter sparks?
- Z
  zacharyortizSep 16, 2025
  If your Trane Technologies Air Conditioner (YC’s only) isn't heating, and the GV doesn't energize, but the CFM runs and the igniter sparks, here's what to check: * There may be a wiring or terminal failure. Verify the presence of 24 VAC between the IGN J1-7 terminal to ground. If not present, check the wiring and terminals and repair or replace if necessary. * The GV may have failed. Measure the voltage between TH and TR on the gas valve (GV). If 24 VAC is present and the GV will not open, replace the GV. * There may be a pressure switch failure. Verify that the input gas pressure is not below the minimum set on the low gas pressure switch.

  If your Trane Technologies Air Conditioner (YC’s only) isn't heating, and the CFM runs, the GV energizes, but the igniter doesn't spark, consider the following: * The flame sense rod may have failed. Check for continuity between the rod and ground and replace the flame sense rod if there is no continuity. * There may be a wiring or terminal failure. Check wiring and terminals and repair or replace if necessary. * The spark igniter may have failed. The spark igniter should fire when heat is called for and 155VAC is applied. If no spark, replace the igniter. * The high temp limit switch may have failed. Check for continuity across the high temp limit switch and replace if there is no continuity.

What to do if Trane Technologies Voyager 3 power exhaust fan cycles on and off?
- E
  Eric BrooksSep 12, 2025
  If the power exhaust fan on your Trane Technologies Air Conditioner is cycling ON and OFF, it could be due to: * The Space Pressure Deadband being too narrow. Increase the Space Pressure Deadband. * The Space Pressure Setpoint being too high or low. Verify Building Pressure with maximum building exhaust enabled. Adjust Space Pressure Setpoint accordingly.

Why Trane Technologies Air Conditioner will not heat (YC’s only): CFM will not run, igniter sparks, GV is energized?
- E
  Emily LeonardSep 12, 2025
  If your Trane Technologies Air Conditioner (YC’s only) isn't heating, and the CFM won't run, but the igniter sparks and the GV is energized, check these items: * The CFM may have failed. Check the CFM and replace if necessary. * The CFM capacitor may have failed. Disconnect the BROWN wires from the capacitor, test it, and replace it if necessary. * There may be a wiring or terminal failure. Check the wiring and terminals and repair or replace if necessary. * TNS3 and/or 4 may have failed (460/575 V units only). Check for 230 VAC at TNS3 and/or 4 secondary, between Y1 and Y2. If 230 VAC is not present, replace TNS3 and/or 4.

Why Trane Technologies Voyager 3 Air Conditioner economizer goes to minimum position, and will not modulate?
- D
  David Gonzalez MDSep 8, 2025
  If your Trane Technologies Air Conditioner's economizer goes to the minimum position and won't modulate, here are potential causes: * The OAS may have failed. Check the OAS at connector P8 by disconnecting P8 from J8 on the RTRM. Check resistance between P8-1 and P8-2, refer to the Resistance versus Temperature Chart. Replace the sensor if necessary. * The DAS may have failed. Check the DAS at connector P14 of the Symbio™700 module. Check for resistance on P14 of the Symbio™700 module, refer to the Resistance versus Temperature Chart. Replace the sensor if necessary.

What to do if my Trane Technologies Air Conditioner power exhaust will not operate?
- J
  Jennifer RobinsonSep 6, 2025
  If the power exhaust on your Trane Technologies Air Conditioner isn't working, here are a few potential causes: * The exhaust motor may have failed. Check the exhaust fan motor and replace it if necessary. * The XFR may have failed. Check the exhaust fan contactor (XFR) and replace it if necessary.

What to do if Trane Technologies Air Conditioner ODM 3 and/or 4 will not cycle?
- M
  Michael MorenoSep 4, 2025
  If ODM 3 and/or 4 won't cycle on your Trane Technologies Air Conditioner, here's what you can check: * The OAS may have failed. Perform an OAS Resistance/Temperature check and replace it if necessary. * There might be a failure in the wiring, terminals, or OFC3 contactor. Check these components and repair or replace them if needed. * ODM3 and/or 4 may have failed. Check the ODM and replace it if necessary. * ODF20 may have failed. Check for proper voltage and contact closure. The ODF20 relay has a 24 VAC holding coil. If voltage is present, replace the relay.

What to do if CPRs will not operate, but ODMs will on my Trane Technologies Air Conditioner?
- L
  Lisa AdamsAug 21, 2025
  If the CPRs (compressor protection relays) on your Trane Technologies Air Conditioner aren't working, but the ODMs (outdoor fan motors) are, possible causes include: * A compressor failure. You should test the compressor both mechanically and electrically, and replace it if necessary. * Failure of wiring, terminals, or the mechanical contactor. Check these components and repair or replace them as needed. * LPC1 has tripped. In this case, perform a leak check, repair any leaks, evacuate the system, and recharge it. Also, check the operation of LPC1.
