Fault codes covered
39-58
Code 39-58 originates in the VFD control when fan motor feedback signal (FG) is not received while a Vsp value has been sent to fan motor for 30 seconds. The fault can also be set when speed error between feedback and command is greater than 100rpm. This fault should never occur because code 39-15 will be declared after 10 seconds. When fault is active, compressor and fan are shut down and lockout time is 30 minutes. Internal electrical damage is likely causing FG feedback to not be received by VFD. Replace fan motor 1st, then VFD.
