Installed a 20K gen to run 5 ton a/c and a couple of small appliances and well pump, After electrician left a circuit board burnt up in the a/c. Any ideas?

Normally when you run out of fuel, you burn out and wreck the fuel pump, they are small, turn very fast and it is the fuel that lubricates and cools them. No power though? check the link for help

please follow this steps and fix it. Otherwise call some electrician. God bless you
The circuit trips again. 2 issues could be causing this:

• Overloaded circuit: Use fewer devices simultaneously or try moving certain devices or small appliances to a different area (use another outlet and circuit). Try resetting.
  
• Electrical short: If your circuit is not overloaded, but the circuit keeps tripping, then this is likely the problem. The appliance or electronic device could be causing this short, or there could be faulty wiring in the walls. Consult a qualified electrician.
  

If you were able to find a supplier who sells just the board then by all means, yes. Chances are that you will not (since it is such a small appliance) and if you do, it may be just as much as an altogether new waffle maker. I do not envy your waffle-less days.

I assume you mean tonnage. If you are looking for the amp amount to run a circuit to your aircond. here is rule of thumb: 2 ton is a 20 amp circuit (requires two 20 a breakers for a 230volt single phase unit)
3 ton is a 30 amp circuit (230v 1 phase)
4 ton is a 40 amp circuit (230v 1 phase)
5 ton is a 50 amp circuit (230v 1 phase)

all these require two breakers, and both breakers should be joined together.

That does not sound normal at all, I have a Goodman Heatpump and the Fan on the Evaporator (outside unit) should run as soon as it starts up!
The only delay you should be seeing is when the unit starts, the fan in the AHU starts 5 seconds after and runs for about 1.5 minutes after shutdown.

Hello. Let me try to help you. Since it is not running at all and stopped suddenly, I would first suspect that you lost power to the unir,

Check to see if there is power getting to the air conditioner. If it is a 110-volt unit, plug a lamp or other device into the same outlet the air conditioner is plugged into. If there's no power, check the fuses or circuit breakers. If there's still no power, you will need to contact a qualified electrician to restore power to the outlet.

If there is power to the appliance but it is still completely dead there may be a problem in one or more of the following areas:

• Wiring (Inspect for any broken or burnt wiring)
  
  
• Thermostat
  
  
• Compressor
  
  
• Overload and/or relay
  
  
• Selector switch
  
  
• Control board
  
  

Work on these areas of an appliance may require help from an appliance repair person or other qualified technician.

Get back to me and let me know if the problem has been solved. I really do want to help you.

There is no way to boost the amount of electricity to your kitchen, short of having an electrician run additional outlets on a new circuit. It sounds like you have too many appliances plugged into one circuit. Most kitchens built since the adoption of building codes have two small appliance circuits, usually on opposite sides of the room. Try moving the electric kettle across the room. If that doesn't work, try unplugging or at least not using the toaster, toaster oven, electric griddle, coffee maker, microwave, or other high demand appliances at the same time.

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.

heat the deflection board with a hair dryer 1-2 min before turning on tv
