If the pressure switch wiring is incorrect, correct it. If that doesn't solve the problem, replace the pressure switch.
What to do if A.O. Smith Water Heater pressure switch remained open?
If the pressure switch remained open, it could be due to incorrect pressure switch wiring, incorrect connection of pressure switch tubing, or an obstructed air intake or exhaust. Address these issues accordingly.
What causes A.O. Smith Water Heater error in the hot surface ignitor circuit?
An error in the hot surface ignitor circuit may be due to incorrect or unsecured wiring; ensure all wiring is correct and secure. Alternatively, the hot surface ignitor may need replacement.
What to do if A.O. Smith GPCR Water Heater system in lockout?
If the system is in lockout, it might be because the gas supply is off or too low to operate. Another cause could be a hot surface ignitor not positioned correctly. Also, check for low voltage to the water heater, or incorrect electrical polarity to the unit, and correct it.
What to do if A.O. Smith GPCR Water Heater has hot water odors?
Hot water odors can be caused by high sulfate or mineral content in the water supply. Drain and flush the heater thoroughly, then refill it. Bacteria in the water supply can also cause odors, so chlorinate the water supply.
What to do if A.O. Smith GPCR has yellow flame?
A yellow flame may be caused by dirt in the burner ports. Turn off the heater and gas, then clean the burner head. It could also be caused by a restricted combustion air path. Check the dilution air intake, exhaust venting, and air openings in the bottom base pan for obstructions or blockage. Insufficient dilution air for proper combustion is another potential cause, so check the dilution air intake for obstructions or blockage.
What to do if A.O. Smith GPCR Water Heater vent pipe too hot?
If the vent pipe is too hot, it could be due to a defective air flow restrictor. In this case, take the unit out of service immediately and call the manufacturer’s representative. Another cause might be insufficient dilution air mixing with flue gases, requiring proper dilution air for combustion. If the dilution air is too hot, check for nearby heat sources or blockages of the dilution air intake. Finally, an incorrect burner orifice can cause this issue, so install the correct orifice.
Why is my A.O. Smith GPCR leaking T&P?
A leaking T&P valve may be due to thermal expansion in a closed water system; install a thermal expansion tank, and do not plug the T&P valve. It could also be caused by an improperly seated valve; check the relief valve for proper operation, and do not plug the T&P valve.
