SOURCE: Goodman GMP125-5 limit switch open

There may be as many as 6 limit switches on the furnace. The first thing to do is turn off the power to the furnace. Look around the burner box. You will see possibly 3 small maybe brown plastic swithes with two wires to each and a button between the wires. Press the button on each one. If it clicks that's the one tripped. There may also be the same kind of switch(s) in the blower compartment. There's a self resetting limit on the middle of the furnace it also has two wires but looks like a black or dark brown plate about 2 1/2 X 3 1/2 inches. You have to check that one with an ohm meter. If any of these switches are tripped there is a reason. Check your filter and overall air flow. with low airflow the furnace may overheat. The switches around the burner box are roll out switches. Watch to see if flames are coming out of the burner area. especially when the blower comes on. DO NOT bypass any of these switches. Call a certified tech. to check it out.

SOURCE: Mine has 7 red blinks and wont come on. i pulled

No, your done. Now replace the Y-Main, that's the large one you found the fuse blown on and replace the two buffer boards that the Y plugs into. Those are the two at the far left. The part numbers are on the boards. So that's 3 boards you will need. sometimes they sell the buffers together as a pair which is cheaper. DO NOT buy from second hand resellers. Always buy new when it comes to plasma sets.

Green power light only on trevi exclusive


When power is turned on, the coffee selection button should blink during warming up. If it is not blinking then the following i possible:
1- The electronic sensor is bad. It is clamp mounted on the boiler to sense temperature and send message to control board to turn the heating off when it is ready to make espresso. The blinking light will be fixed to display this.
2- The heating element on the boiler is bad and not heating. The electronic sensor cannot relay any temperature as it is.not sensing the heating.
3- The electronic control board is bad and not sensing the temperature.
The machine should be opened up to test the sensor or the neating elements, and replace what is bad..

Igniter isnt lighting


IF YOU LOST POWER WHEN FURNACE WAS RUNNING IT TRIPPED ROLLOUT SWITCHES AND POSSIBLY THE HIGH LIMIT . IN CENTER OF ROLLOUT SWITCHES IS A LITTLE RED BUTTON THAT YOU RESET . YOU CAN ALSO TRY FINDING HIGH LIMIT WITH POWER SHUT OFF TO FURNACE PULL BOTH WIRES OFF HIGH LIMIT AND USE PAPER CLIP TO JUMP BETWEEN THE TWO WIRES MAKE SURE YOU DONT SHORT OUT AGAINST ANY METAL WHEN YOU TURN BACK ON IF IT WORKS YOU NEED A NEW HIGH LIMIT SWITCH.

When the furnace shuts down, blower kicks on and off


Probably residual heat kicking the fan limit control on and off. Readjust the settings on the fan limit control.

Red boiler light will not go on. The boiler does heat up.


Open the steam valve when you turn the machine on that will vent out the boiler, keep it open until it starts to hiss slightly and produce small steam bubbles, then close and machine should heat to temp. If that solves your problem then the vent valve needs to be replaced, until then you can turn using the steam valve open trick.

Blinking red light no heat


It sounds like you are actually in lock out. Recycle is when during a call for heat, the flame goes out, the unit will try to restart itself. Hope this helps

Hi,

Are you getting Hot water and Heating?

The reason i ask is because I don't think you have a problem.

On this boiler it has a 'pump over run' thermostat incorporated into it, this ensures heat escapes from the boiler by using the pump to cool it down.

If you are getting hot water and heating, leave it well alone, if you reset the boiler this can have adverse effects on the boiler and evenually cause malfunction.

However, if you find that you are not getting Hot Water or Heating, then the most common fault on this boiler is the PCB (Printed Circuit Board) it is the 'brain' of the boiler and the most common fault on this make. (£160 + vat)

I hope this helps,

Steve
