Refrigerator cooling but not real cold, freezer freezes ice but
Doesn't seem cold enough. Checked seal and cleaned coils didn't help. Seems to be running. Frost is on the inside of the freezer and there is no pooling of water at the bottom, the pooling has been happening for the past few month but not there isn't any water. Please help do i need a repair man or is there a part i can replace.

***UNPLUG THE UNIT***
Take the cover off the back where the tubes go from the compressor into the freezer. If you can see into the freezer AT ALL, you have a mouse issue. Plug this hole with expanding foam. If you're getting room air into the freezer and your door seals aren't coming apart, it's usually from the rear. Make sure to melt all ice that formed in the bottom of the freezer before you plug it back in.

If the freezer is set at the lowest temperature the compressor will run continuously causing this. Also if humidity is high where you live and the seal on the freezer isn't sealing properly the excess moisture will cause it to ice up.
Okay, here's a bunch of info in the order I would troubleshoot since the one year warranty expired.
1) The water filter might be clogged. Try just removing it to see if it makes ice. If it does change the water filter.
2) The water inlet valve might (still) be defective. The water inlet valve is an electro-mechanical valve. The coil can show good for continuity and still not let the water thru although you didn't say if it worked when he left. if recently replaced it should be under his warranty.
3) The water pressure in the house might be too low. The water inlet valve which supplies water to the ice maker is designed to work with a minimum of 20 psi of water pressure.
4) The door switch might be defective. When the freezer door is opened the freezer door switch does two things, it turns on the light in the freezer and turns off the ice maker and dispenser. If the door switch fails the dispenser will not turn on. The switch can be checked for continuity with an Ohm meter. If it doesn't have continuity it should be replaced.
5) It could be that the ice maker assembly itself is defective. The freezer temp should be between 0-5 degrees for the ice maker to cycle properly. There are several components in the control module of the ice maker that can fail and most are not sold separately. Also, ice makers have a relatively short lifespan and so it might not be worth fixing. If other, simpler parts like the water inlet valve or shut off arm have been ruled out, and the only thing left is the ice maker itself, replace it as a unit. Not as expensive as you may think...Under $100
6) The icemaker module at the front might also be defective. The module has a motor that cycles the ice ejector arms around to push the ice cubes out when the ice maker thermostat closes. It also has contacts in it for the mold heater and water inlet valve. The motor or contacts of the module can fail. Usually there are test points in the module that a service person can use to determine if there is a problem with it or one of the related ice maker components.
7) The icemaker mold thermostat might be defective. Inside the control module of the ice maker is a thermostat which monitors the temperature of the ice mold (ice tray). Once the mold reaches the proper temperature the ice maker starts a harvest cycle by ejecting the ice cubes and refilling with water. If the mold thermostat is defective the ice maker doesn't advance. The thermostat can be checked for continuity. Replace it as needed.The freezer temp should be between 0-5 degrees for optimum performance.
No error code.
Incoming water is very cold.
Before calling service technician:
Catch up on maintenance.
Clean water filter.
Delime heat exchanger.
Check for crossover
Check water flow is high enough
Set temperature lower.
Install tempering tank.
By sealed unit you mean that the burner air comes from outside of the house?
You have checked the heat exchanger for cracks by removing the burners and looking with a mirror and flashlight, correct, or had a service tech so?
The furnace burners have enough air and are burning clean (blue) with just a tip of orange at the end? You bought the house new and the fireplace has never been used? If it has been used to clean smoke for the house for whatwever reason I woudl start by havign the ducts cleaned.
Another possibility I have seen is insolation inside of ductwork breaking down.
