Had a customer a while back stating the unit was blowing fuses in the disconnect.
initially I didn't even take a thermal image. Due to the condition of L3 fuse just by
looking at it with the naked eye. I told them to call an electrician. An electrician
came out and stated it wasn't the disconnect. The company I was working for didn't
always send back the same tech. After other techs replaced the motor and heating
elements costing the customer well over $4,000 USD. That was just for the work
my company did. The customer stated they were replacing the fuses twice a day at
$10 a piece. About six months later I get a call out there, the issue was never fixed.
Told the customer the same thing. Customer was pissed, and arranged for me to
met the electrician. I met them there one master and one apprentice electrician.
Spent two or three minutes trying to explain the issue with the electrician, with no
luck. Got the thermal camera out. The Apprentice said, "We got to get one of
those". The Master turned to him and said "Callate!". Which is "Shut up" in
Spanish. Then we all agreed what the issue was. After the disconnect was
replaced the customer didn't have any other issues.
