Re: fuse in A/C unit
This fuse is on the control board inside of the furnace. If you take the outside cover off you should be able to see it on the upper left habd side of the circuit board. It probably is either a 3 or 5 amp fuse depending on the size and/or model of your unit.

I can sympathise, I have had three go wrong in the last few months! In every case it was the element, I suspect it will be the same with yours and there is not much you can do except replace the kettle.
If the plug has a fuse, you could try changing it, but it didn't make any difference with mine. Try to keep the element free of scale, that shortens their life even more. I don't believe it is worth buying an expensive kettle, they don't seem to last any longer than the cheapies.
Generally, the fuses are located in a box outside by the outdoor unit. The box has a door on it and you will probably have to pull a cartridge out and the fuses will be behind the cartridge. If you don't have an ohm meter to check the fuses , just go to home depot, lowes or another hardware store where they can check them for you. Be sure to check the circuit breakers too.
Lisa, I can understand your frustration. I suspect that any replacement will have to be approved by Ruud. But, in most cases, they will probably want it to be repaired and they will pay the cost, if it's a part that is covered under the warranty. Certainly, you can broach the subject with the serviceman, but I don't think he'll be the one to make the call on total replacement. That is, unless, he owns the company and they were the one's who originally sold and installed it. In the meantime, contact Ruud's Customer Service Dept (the number should be in your Owner's Manual) and calmly explain your frustration and dissatisfaction with their product. That may go a long way, in either getting a new unit or the repairs paid by them. Be sure that you have your proof of Purchase handy, before calling.
You may have fuses. Many outdoor units will have a box mounted usually on the side of the house with fuses inside. There usually is a door you have to flip to the side or up, and there will be a "pull out" cartridge with fuses behind it. If you don't have an ohm meter to check the fuses just replace them both and hopefully this will solve the problem. Many other times I have seen (this time of year) ants and other pests get into the out door unit contactor to where the electricity cannot flow to the components. This contactor is located in the electrical section of the unit, it is where the power lines are connected and may be a brown or black colored square box with all the wires connected to it. This is an automatic switch turned on by the thermostat. Believe it or not, ants can crawl up into this and get caught in the contacts. Be sure to turn your power off before you open the elect. part of the air conditioner.
It more than likely has the bearing or bushings worn. Usually better just to take the motor out and get a new one unless there is a place that can replace bearings nearby. This kind of repairman is very few and far between.
Before calling a repairman, check your self by a volt meter.Confirm power is there in your indoor unit.If there green or red light in the unit displayed or not. If yes, try with your remote. If not check your PCB for fuse blown. Replace the fuse and check again. Indoor unit display light and no work by your remote means communication error between your remote and unit. Try with other remote. If o.k. replace your remote. If not, problem with PCB receiving sensor. Repair it. Thanks and hope it's helpful?
I don't believe " Miller" brand has a manual reset for high pressure. The disconnect box on the wall next to the out door unit is fused. It has a pull bar in it and has the fuses attached or behind it, depending on the box. The fuses are " slow blow " fuses, a little more expensive than normal, but if one is bad, change them both. Only check them with the breaker turned off. If you cannot check them it would be worth while replacing them. Chances are that is your problem. Most of the time that is all that is wrong, but there is a chance that something wrong in the electrical for the outdoor, ie capacitor, compressor or fan motor, in which case you need a service tech to make that call.
if the fan motor outside let go it could overheat the compressor which he should have known before he replaced the motor. also there is no way of knowing if there is enough freon in the system if the compressor does not start,your best bet is to get another repairman as a second opinion
