So I woke up and noticed that it was cold. So, I went to the thermostat and saw that the little screen was off. After opening up the handler, I saw that the 5 amp fuse that is on the Fan Coil Circuit Board was blown. I continued to look around for anything out of the ordinary. After not seeing anything, I put in a new fuse. It started to work, sat there a little while and everything looked good. Later I noticed that the screen on the thermostat was off again, and yes the 5 amp fuse blown again. List of items I did: Visually inspected for burnt or frayed wires and burnt spots on the circuit board. Found nothing. Measured handler is getting 220. Measured that the transformer is getting both legs of 120 and that the secondary side is out putting 24v Traced the thermostat wires from the handler to the thermostat, and also traced the wires going from the handler to the outside unit. All measured good with no opens. Other items of information: I have to handlers. One for each story, and yes the other is operating great. No new nail holes or anything. Thermostat does not have batteries, and I switched with the other thermostat and the other is still working fine. Model:FA4CNF024 Any help would be greatly appreciated.

Does anyone know where I can find a coil for a Trane 3 ton air handler Model# TWVo36B140A1. My outside unit has no issues and is in great shape but the coil is leaking on the inside unit. I'm being told by a local contractor that the coil cannot be ordered anymore and they said I need to replace the whole system indoor and outdoor. Any leads, please reply! Thanks!!
