6 Easy Ways to Fix Trane Gas Valve Circuit Error

The Trane gas valve circuit error is not a pleasant thing to have when you’re trying to heat your home. This is usually an indication of some sort of internal problem with the gas valve and has to do with how much current the valve can handle before it trips for safety reasons. To fix this problem, you’ll need to reset the circuit, and this means that you’ll have to shut the gas off for at least 30 minutes to do so. Once that’s done, you can begin troubleshooting the Trane gas valve circuit error again so that you can repair it once and for all. When something like this happens, it could be due to any number of factors, but one thing that might also help is reading our ultimate home heating guide!

Check the circuit breaker

One of the first things you should do if you have a Trane gas valve circuit error is to check the circuit breaker. If the breaker is tripped, this may be where the problem is stemming from. It is best to have a professional check this for you, but you can also try resetting it yourself by following these steps: First, shut off the circuit breaker. Next, check the connections to see if there are any signs of damage. If everything looks fine, try resetting the breaker. If the circuit breaker trips again, you’ll have to call a professional. If everything checks out and there’s no sign of damage, it’s possible that the circuit breaker itself is faulty and needs to be replaced. Make sure that the circuit breaker is rated for 120 volts and 15 amps. If it’s not, you’ll need to replace it.

Check the gas supply pressure

The gas supply pressure is supposed to be somewhere between 28 and 120 PSI, and if the pressure is too low, you’ll get a Trane gas valve circuit error. What you should do if this is the case is to check the pressure at the gas meter and if it’s below 28 PSI, try turning the gas on and off at the meter until the pressure reaches the correct level. If you don’t see any changes, it’s possible that the pressure regulator is faulty and needs to be replaced.

Verify the Gas Valve Rating

Not all gas valves are created equal, and some are better than others at regulating heat. If you’re experiencing a Trane gas valve circuit error, you might want to verify the rating of your gas valve to see if it’s defective and contributing to the problem. Ideally, you want a Type 1 or 2 gas valve. Type 3 is intended for outdoor use only. Type 1 gas valves have a maximum current rating of 15 amps. Type 2 gas valves have a maximum current rating of 20 amps. If your gas valve falls outside of these parameters, it’s possible that it’s defective and needs to be replaced.

Check the Gas Valve Circuit Continuity

If the rest of the circuit checks out and you’re still getting the Trane gas valve circuit error, the next thing you should do is check the circuit continuity. This will tell you if there are any breaks in the circuit and if there’s anything wrong with the wiring. To do this, you’ll need a multimeter set to continuity mode. You can follow this guide here to use a multimeter to test the circuit continuity. If you find that something is wrong with the circuit, you’ll need to repair it before you can try to reset the circuit again.

Check the Resistance of the Coil and OP Amp

Now that you’ve checked the circuit continuity, it’s time to check the resistance of the coil and OP amp. If either one of these things is broken or faulty, it will show up on your multimeter as an open circuit and shouldn’t be there. If you find that there is an open circuit, you’ll need to repair it before you can reset the circuit again. To test the resistance of the coil and OP amp, you’ll need to follow this guide here. If you find that either one of these things is faulty, you’ll need to replace it before you can reset the circuit again.

Conclusion

The Trane gas valve circuit error is a problem that will pop up from time to time, and it can be especially frustrating when it happens right when you need your heat most. The good news is that most of the time, these issues can be fixed with a little bit of troubleshooting. Most of these problems stem from the gas valve, so if you’re getting the Trane gas valve circuit error, start there. Once you’ve fixed it, you can get back to enjoying your home’s heat again.
