Brand New 2 weeks old 4 ton Trane compressor leaks a lot of water onto pad

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.

The video gives you an example of the defrost cycle!

No power at interior unit. power everywhere else

If this is a mini split ductless there is a control wire with 3-4 wires inside (normally red, white, blue and green) that is connected from the outdoor unit to the indoor unit. This wire feeds voltage from the o.d. unit to the I.d. unit. If all connections at the o.d. unit are good, then check for voltage at these connections at the o.d. unit. If no power at these connections then a circuit board has faulted. Call a tech. and have a tech support number ready (1-800#) in case your service tech don't have it.

Baxi banging noise

noise in water pipes is called water hammer and is when the water flow pulsates from an inconsistent flow. Water has mass and when stopped suddenly there is a pressure build up which moves any loose pipes. It can be fixed by putting more securing or mounting saddles on the pipe to hold it steady or you can get a pressure accumulator and it takes up the pressure build up and stops the noise. It is most prevalent when sudden stop taps are used such as ceramic taps or stop cocks and less so when you have to screw down the tap to shut off the water.

Timer light on fujitsu heat pump flashes not heating

the light flashing indicates there is a problem. you can try reseting the system by turning the power supply off and back on again 30 sec later, if the same thing happens you need to count the number of light flashers and that relates to a fault code

I'm having a similar problem. My water heater is Eternal GU195S. It will heat up the water it's in the tank so I will get hot water for a few minutes. Then whenever the system tried to heat up on-demand, it will not heat up and gave E02 error. If I stopped drawing water, the E02 error will go away and the temp setting I had will come back on. What could be the problem? I currently took it out of service and set it up outside my work shop for testing. Thanks.

Our Rinnai C85 tankless water heater is used for radiant heating. During the heating season it will occasionally throw a "12" code and cut out. It will reset and run for several days. Technician...

Sorry to read about your problem, I hope this helps you out.

Ok your code 12 is a gas issue, or this listed below

Check that the gas is turned on at the water heater and gas meter. Check for obstructions in the flue outlet.
Ensure gas line, meter, and/or regulator is sized properly. Ensure gas type and pressure is correct. Bleed all air from gas lines. Ensure proper Rinnai venting material was installed. Ensure condensation collar was installed properly. Ensure vent length is within limits.
Verify dip switches are set properly. Ensure appliance is properly grounded. Disconnect keypad. Disconnect EZConnect or MSA controls to isolate the problem. Check power supply for loose connections.
Check power supply for proper voltage and voltage drops. Ensure flame rod wire is connected. Remove flame rod and check for carbon build-up; clean with sand paper or emery
cloth. Disconnect and reconnect all wiring harnesses on unit and PC board. Check all components for electrical short. Check gas solenoid valves for open or short circuits. Remove burner plate and inspect burner surface for condensation or debris.

your manometer levals should be around 3-4

if you are running other gas appliances, like pool heater

My outdoor unit keeps freezing over. Why?

Hi, what is happening is this is a heat-pump split system. When it starts to ice the outdoor coil up, this unit has a defrost board, along with defrost thermostats that are clamped around copper lines with in the condenser unit. Both time and temperature activated. The board is time, while the thermostats are temperature. On the board, you can see 3 intervals, 30, 60, and 90 minutes. This is set by the factory and will have a small wire attached to one of them, maybe the 30 minute, all depends on the unit. If it doesn't go into defrost, and the ice keeps building and building, more then likely the defrost board is your fault. They are a problem on most all heat pumps. When the unit goes into its defrost mode, you will see the condenser fan motor stop, the reversing valve will shift into the cooling mode send hot gas through the outdoor coil to defrost all or most all of the ice. It will stay in this mode until time is up or the thermostat senses the line temp and tells the board to start the heat again. If you don't see this happening at all, you can replace this board on your own if you are able, as they are very easy to change out. Only if it is not going into this mode should you change it. Its normal for ice to form on the unit, but not to stay and not to defrost. If you are having to shut it off or using a hose to remove the ice, replace this board. You will need to get the part number off of the board, all of your thermostat wires also connect to this board, so you can make a drawing on how all is wired and take the board with you, or take all numbers from board and the model and serial number, and name of the outdoor unit with you to a appliance parts house to get one. If you have a Granger's anywhere close to you, this will be your best bet to find it. You have to be a C-20 or C-38 contractor to get one at a heating wholesale house. If this unit does go into defrost, and is heating OK, like I said, ice is a normal thing. There are only 4- screws holding the board in place. Turn off the power at the box near the unit. The board has 4 stand offs where the screws go through to keep it from grounding out to the metal behind it. I hope I have been of help to you. Please rate me on my help. Thank you, and I wish you the best.

I have a Certikin Genie swimming pool boiler that is showing the word GAS and i can smell it. What should i do?

You could try resetting this as it could be caused by several factors (blown heat exchanger being one as Karl mentioned).
Hve you tried resetting from in Service Mode ?

To get to Servce mode you need to go ino User Setup Mode first (turn off the boiler via the panel switch - then hold the Lock/Reset button whilst turning back on). Once in User Setup Mode if you rotate the thermostats all the way clockwise (it should display the software version) Then press and hold the Lock/Reset button for 3 seconds.
This should put you into service mode and it is now possible to change/reset some of the control parameters.
If you try resetting the error.

This issue may be caused if the Flue or water stat is tripped (in which case reset the stat). If th Fan resistor remains open in the circuit then you will need tsomeone out to investigate as that may cause the GAS error too.

COuldalso be the Valve coils are faulty in wich case they need replacing (agians I would get an engineer outto confirm and do that).

I'm suyou probably tried all this but just in case...

If the roblem is solved can you advise what fixed it ?
