Question about Heating & Cooling
I have a model 58GP100JA the control board PT# HH84AA020 has just been changed for the second time. The A/C side of the unit work fine but when changed over to heat the burner will come on but the blower will not. When it appears that the high limit breaks the gas valve then the blower will come on. When the blower quits the burner will come back on. On the insert that comes with the control board it mentiones a jumper between Gas 1 and Gas 3 on the original board that needs to be placed back on the replacement board. There was no jumper on the board that I changed out so there is also no jumper on the new board. Would this jumper correct my problem.
How long does the burner stay on before the limit takes it out. The board has a delay for the fan in heat and it may be to long. If your unit had cycled on high limit to much it may have a bad limit switch. The limit is so low it cuts out before the fan has a chance to come on. See on the board if has an adjustable time deley. Should 30 60 90 set to thirty. Keep in touch rus
