I have a Ruud air-conditioner/heat pump and it blows 5 amp fuse.
I have a 3 year old 3 ton Ruud air-conditioner/heat pump. A couple of weeks ago I noticed the outside unit was not running and after checking found the compressor contactor points burned (I replaced them). The unit still would only run if I depressed the contacts with a screwdriver. I then checked the air handler in my attic and found that the control transformer was faulity (no low voltage), so I replaced it. I thought I had solved my problems until I turned the thermostat to the cool position and it blew the 5 amp fuse located in the air handler. The blower will still run in the "on" position, but only until I switich to the cool position,

Re: I have a Ruud air-conditioner/heat pump and it blows...
It sounds like the thermostat wire going to the condenser is ground, It either got pulled loose and is touching the housing or as in most cases the wire got cut or was chewed by an animal. You need to turn electric off to both devices and physically inspect the thermostat wire going from the air handler to the outside unit, also inspect where they connect inside the unit. When you find the break, cut and strip each individual wire and securely wire nut each conducter red to red white to white and so on. There you go all fixed. That's when I give you the bill for $75...except this time you write that check to yourself. Good Luck

If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.
That's a complicated system that needs a qualified technician to service it. Lots of people can install them and they run fine, for a few years. Your indoor unit, operating on 2 heat elements, will feel like its blowing cold air even though its heating, just not so well. And not like you are accustomed to. Each element (5kw)=22.7amps, on average. So 3 elements operating should trip a breaker. Its probably been operating on 2 heat element plus the heat pump. And now you have trouble with the heat pump. If you can't TRUST the guys working on your equipment, try someone else. A second opinion. Normally a 3 or 4 ton unit will have 15kw heat installed, heatpump or not. 5 ton, 20kw. If yours is a 3-4ton, cooling, the 100amp(or normally two 60 amp) breaker should have been installed upon equipment change out. If yours is blowing cold all the time, something is wrong with your heatpump. The electric heat inside operates only when the heatpump can't keep up(real cold outside), the heatpump is in defrost(then it's actually in cooling mode), or if you have the tstat in aux/em. heat. Try a local trane dealer? Of a technician with 15-20 yrs under their belt. A trane dealer should have trane tech support also. BIG HELP!!!
Ruud parts warranty from factory is 5 years, the capacitor has possible gone out, it will be in the contol compartment on the out side unit and is a dual run capacitor that controls the compressor and fan motor. Recommend if capacitor is bad to replace entire capacitor. As Stated above the parts are under warranty if under five years old. To verify age the date code is in the serial number after the "F" **** week/year of manufacture. Also outside unit has independent power supply so check fuses if any and circuit breaker.
If its not a heat pump- check the white wire connection on the thermostat. If it IS a heat pump, check the blue wire connection on the thermostat. Both of these wires control the heat in their respective systems.
Hi, there are 12,000 btus per ton of cooling. You go by the numbers in the model number. I see you have a 030 which would be a 21/2 ton. I also see a /36a which could stand for a 3 ton, but its the 030 number you want. It is a 2.5 ton unit, no question! 2x12 is 24+6=30,000 btus, a 21/2 ton unit. Hope that cleared it up for you.

A "Heat-Pump" is also known as a reverse cycle air conditioner, this means on heat the outdoor unit acts like the indoor section and vice versa. So in all probability you need to have it leak checked and recharged.
I would suspect you have a problem in the defrost circuit of your heat pump. there are a couple of things you can try. first just run the system on emergency heat and see what happens. you could have a defrost board that is shorting when it kicks into defrost. it sends a signal back to the furnace so it will come on during defrost. if you do not blow a fuse as long as you are running in emergency heat, i would suspect the defrost control board. also you could have a dead short in the wire that runs from the "w" terminal on furnace control board, out to the heat pump. keep in mind that any of the wires could be the cause and i am just tying to give you the most common things. your furnace will still run if you unhook all the low voltage wiring out at the heat pump. if you do this and stop blowing fuses. you know it is something on that wiring. goodl luck.
