Hello, were those dual element or 'one time' buzz fuses. what amperage were they rated at.

Do you have a multi meter to measure ohms with at the compressor itself?

We can go from there.

I thought i talked to you free last year when my heater didn't work. and i did this over several days. I thought i could do that this time i have an appt: because nothing ever happens when a 100 other things aren't going on. I hope i can get back with you later today and my fee will still be honored. I also can not afford to pay every month i need an occasional fix. if i were not poor i would hire people to do this junk. thanks i'll be back later mlk
