How to troubleshoot a Trane Air Handler motor that fails to start?
- I
  irussellAug 19, 2025
  If the motor in your Trane Air Handler fails to start, several issues could be the cause. First, check for a blown line fuse or an open circuit breaker and replace the fuse or reset the breaker if necessary. Also, inspect the wiring, comparing it with the diagram on the unit to ensure proper connections. Confirm that the current supply matches the motor nameplate recommendations; if not, contact your power company. Finally, check that the fan rotates freely, as mechanical failure could also be the reason.

What to do if Trane Air Handler motor does not come up to speed?
- T
  Travis JamesAug 21, 2025
  If the motor in your Trane Air Handler isn't reaching full speed, it could be due to low voltage at the motor terminals; check the voltage across the AC line and correct any loss if possible. Another potential cause is undersized line wiring to the motor, which should be replaced with larger wiring.

  Matthew BuckAug 28, 2025
  The motor in your Trane Air Handler might be overheating due to a couple of reasons. It could be overloaded, in which case you should reduce the load or consider replacing it with a larger motor. Another possibility is that the motor fan is clogged with dirt, preventing proper ventilation. To resolve this, remove the fan cover, clean the fan, and then replace the cover.

What causes low water coil capacity in Trane BCVE Air Handlers?
- N
  Nicole WilliamsSep 1, 2025
  Low water coil capacity in Trane Air Handlers can stem from several factors. These include: * Incorrect airflow: Check the fan's operating condition. * Incorrect water flow: Inspect the water pumps and valves for proper operation and check the lines for obstructions. * Incorrect water temperature: Adjust the chiller or boiler to provide the correct water temperature. * Coil piping issues: Verify the coil piping. * Dirty fin surface: Clean the fin surface. * Incorrect glycol mixture: Verify and adjust the glycol mixture if needed.

Why is the refrigerant coil capacity low in my Trane Air Handler?
- C
  Cheryl FrazierSep 4, 2025
  Low refrigerant coil capacity in your Trane Air Handler could be due to several reasons. These include incorrect airflow (check the fan's operation), a malfunctioning or incorrectly sized expansion valve (check sensing bulb temperature and valve operation), an incorrect refrigerant charge (verify and adjust), or a condensing unit failure (verify its operation). Other potential causes are coil piping issues, a clogged refrigerant line filter (change the filter core), failure of suction/liquid line components (verify their operation), a dirty fin surface (clean it, avoiding steam), or fin frosting (verify defrost cycle and frostat operation, and refrigerant charge).

What causes a wet interior in a Trane Air Handler?
- J
  Jade BurkeSep 6, 2025
  A wet interior in your Trane Air Handler could be caused by: * Coil face velocity being too high (reduce fan speed). * Improper trap design (design the trap per unit installation instructions). * Drain pan leaks/overflows (repair leaks). * Condensation on surfaces (insulate surfaces).
