A customer request service call for nuisance blowing fuse on RTU AC its a 3phase 240 with high leg. The fuses I replaced were ontime fuses that I replaced with slowblow fuses and after few days they blew again this time just one fuse instead of two. I put meter on them and got 38amp each phase and It cycled a few time with no problem. Customer said they changed thermostat but dont see reason why this would effect ac blowing fuses
As much as they have. The compressors were huming pretty bad even during start up. MY GUESS COMPRESERS ARE WORN. Any ideas I will go back tomorrow because I lost day light, but I know I will get some good advise from you guys.
