Question about Haier Energy Star ESA3183 Air Conditioner
I have the Model# MBE2000 & CAPF4860D6A 16 seer 4 ton heat pump. After two-four hours the heat pump blows the fuse on the circut board in the indoor unit. Is very annoying. I have been replacing these 3 amp fuses at a rate of 5 per day. Started satruday when temps were down in 20's. Furnace runs normally untill the fuse blows then shuts off. Circut breakers are not tripping or anything. Tried to un plug the hudistate and that didn't help. Please any help would be nice. 50 degree mornings ****.
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.
