SOURCE: 3 amp fuse blows after three hours on Goodman 4 ton 16 seer pump

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.

SOURCE: furnace blowing 5 amp fuses

This is caused by a low voltage short. Most often it's the T-stat wires going to the condenser unit outside. Check to see if the insulation on the wires have degraded and replace them if necessary. Also, if the wire has been spliced before redue the joint and weather seal it so that it won't happen again. This is what I do for a living so if you have any more questions, please feel free to ask more questions.

SOURCE: Weather King blows fuse in Criterion II furnace

You probably have a shorted wire between the heater and the a/c. There are two wires that conncet the control power to the outdoor a/c from the heater they should be on terminal c & y in the heater. disconect those two wires and try it again if the fuse doesnt blow you have a short in the wire between the a/c & heater

Look at the contactor on the condensing unit, remove the low voltage wires to the contactor and turn on the system. If the low voltage fuse doesn't blow, replace the contactor.

Coleman furnace dgaa077bdta


The control fuses keep blowing tells me one or more of the control that operate the control on 24 volts is malfuctioning. Most controls operate at about 5 watts and on a clamp on amp meter normally pull about 0.2 amp (p = current x voltage, 5 watts = 0.2 amps x 25 volts) I install 75 watt 24 volt transformer with a resettable overload to save on fuses. I reset the transformer and quickly go to the controls and determine the amp draw. When I find the one >0.2 amps I found the problem. The things to check is the emergency heat sequencer, fan control sequencer, reversing valve for heat pumps, main contactor on the condensing unit and any other 24 volt control loads. I have had to replace the themostat wire because the increase current for the thermostat wire can cause the entire length of wire to form a long heater and cause insulation degradationa and cause the thermostat wire to short out and blow the fuses.
Hope this helps

You either have something wired wrong or you have a direct short in the system. Are you starting the A/C or the furnace? If it's the A/C, it could be a shorted compressor, capacitor, fan motor or it's wired wrong.

Bryant programmable thermostat doesnt keep the temp have to put it on fan instead of auto


My guess is that you have gas heat. If this is the case, sounds to me like your main control board or depending on age of furnace, fan controller is not working. With gas furnaces, it utilizes 2 fan speeds. High for cooling, & Low for heating. Your thermostat only controls the High speed - switches when you turn your fan on & when there is a call for cooling. The only other thing I can think of is it is possible that the Low speed windings on the blower motor are open causing it to not turn on. Most motors have 3 to 4 speeds & only 2 are used. Switch the heat motor wires in the furnace (on the control board) with one that is on a spare terminal.

Furnace blower runs continuously but no heat


sounds like the furnace control (low voltage) circuit is open, or in other words you either have a fuse blown or a limit switch that needs to be reset. Most newer furnaces have a small knife like fuse, usually 3 or 5 amp located directly on the circuit board. Limit switches that have a manual reset are usually located in the fire box just above the burner. There may even be a limit switch located on the blower assembly. If you fuse was blown, you may need to find out what caused the short in the circuit or it will do it again. If the limit switch was tripped, you need to turn the furnace back on and watch the flame to see if there is "roll out". It it continues to trip or blow fuses you need to have the unit serviced.

The furnace wont turn on even though it says it is


not all digital thermostats are compatible with the manufacturers circuit control boards in the furnace. Hunter has had this problem several years ago. Other than that you may have miss wired the unit. usually the furnace is used as backup heat (during defrost) or emergency heat if your heat pump konks out. Are you switching to emergency heat for a furnace call?
