What to do if the Danfoss Controller compressor does not start?
- WwlaraJul 27, 2025
If the compressor does not start, it might be due to several reasons. It could be waiting for the compressor delay timer (check CoP->CSt), a defrost cycle in progress (check CoP ->Pot /Pod), or the line voltage to the compressor might be too low or too high (check dEF ->dit, dot). Also, check CoP->uLi, uLo, uHi.
