Heating & Cooling - Recent Questions, Troubleshooting & Support


Hey bud. Not sure what you are talking about. You have a 2003 Toyota Tacoma SR5 and you see a LED light light that turns on when the thermostat calls for heat. The only thermostat is inside the engine and the coolant temperature is shown to you by means of the coolant gauge. Is this a light or warning light? Is this light on the climate control panel or gauge cluster? I almost wonder if you are combining the engine cooling system with the climate control. Please write back and reword your symptoms for me. Please remember that I can not see what you are looking at. If the description has more details, its easier for me to understand the problem. Good Luck.

I have same problem like yours to my newly installed Fujitsu multi-split system (the first time use since system installed 1 week ago). I rang the electrician who did the installation; he said it must be the units themselves nothing to do with electricity.

Okay, then I rang Fujitsu and their local service agent. They suggested me to switch off C/B for an hour to reset the units. I followed the instruction but the indoor units still did not respond to remote control...

It simply looks like no power supply to indoor units (they are hard-wired to the outdoor unit). So I used a multi-meter to test the power terminals of indoor units (Danger! If you have no idea about this, don't even try! ): it seemed no power supply even C/B is on. I turned to the isolator which next to the outdoor unit. The isolator was making arcing noise when I switched it on and off. The indoor units suddenly turned on for few minutes then died again.

So I figured out the problem is that crooked isolator. I called the unhappy electrician to replace the isolator. End story....

I hope my experience will help you a little bit.

Most gas appliances are designed to operate from methane, butane or propane, though suitable alterations have to be made, line pressure, gas jet size, air mixer and so forth as directed by the manufacturer.

Methane or natural gas has a lower calorific value and needs a higher volume of gas to function efficiently...

I am trying something now as I was told F2 requires you to check the blanket for wear and tear and plug it back in. 3 times doing this should be sufficient. If it still reads F2 it's "gone" Ours is new so it shouldn't be "gone" but here's what I found...Where the plug goes into the blanket there are 4 holes for 4 silver pins. I noticed the 3rd pin was a bit lower than the other 3. It will not move up with pliers so don't force it just return it. check there

Steady light on - normal operation.
One flash - ignition failure.
Two flashes - combustion air switch stuck closed.
Three flashes - combustion air switch failed to close.
Four flashes - limit switch open.
Five flashes - gas valve energized with no call for heat.
Rapid flashing - reversed polarity.

Note: Color of light is green.
