DAYTON 3E133E LIGHTS AND THEN SHUTS DOWN. IT GOES THROUGH THE CYCLE 2 OR 3 TIMES BEFORE IT STOPS TRYING. I REPLACED THE CIRCUIT BOARD THINKING IT WOULD SOLVE THE PROBLEM BUT IT DID NOT WORK. THE ONLY...


After the sparking begins, the circuit board needs to prove the flame is present or it will quit sending voltage to the gas valve, then lock out after a few attempts. Flame proof is 1 microamp (1 millionth of an amp) DC between the flame sensor rod and the ground rod (middle rod). This DC amperage is produced by the current flowing through the flame between those two rods, and up the white wire to the circuit board. The flame sensor rod and the ground rod must be in the correct location, which is about 1/16" from the ceramic grid, maybe even 1/8". Neither rod should be "shorted out" (touching each other or any nearby metal), otherwise current is not flowing through the flame. Make sure the wire connection at the flame sensor rod is not loose or corroded.

Toyo lazer 55 wont ignit took apart cleaned every thing and replaced all gaskets and unit wont start


Check the igniter and make sure it is good. You can check the igniter with an ohmmeter and check the circuit board where the igniter connects for voltage with a voltmeter. A Laser 55 is an old unit and parts are hard to find. Also check the flame rod and make sure the fuel pump kicks on after the preheat time. When you turn it on the blower should start and the igniter should start to preheat the burner. After 3 minutes the fuel pump should kick on. If it is making a loud ticking or thumping sound it isn't getting fuel to the pump. If you do need parts I have an old Laser 55 with some good parts. You can contact me at nitensheaterservice@earthlink.net. Use caution when making checks on the circuit board. If you ground something it is likely to ruin your circuit board and those are not longer available. Turn the power off before removing the flame rod. They have power on them and also can ruin the circuit board if you let them touch anything metal on the heater. Let me know what you find.

Make sure that there are no wires connected to the G terminal on the circuit board. There is a blower relay on the circuit board that is probably bad, replace board.

That pressure switch closes for a run condition. check for continuity between the plugs on it with the induction fan running. If its closed, change the board if not change the switch.
The switch will tell you its pressure rating on the label and its best to just use the same rating. Easiest to get it from a Goodman Parts Supplier. You can order it on the internet, should have a part number on the label or just use the model and serial of the furnace. Locally you will probably have to buy it from someone in the trade.

Heater won't light


Not having a make or model number, I can only give you generic information. However if you add more info, others and myself can give you a better diagnosis.

 

In order for a furnace to start that has an inducer motor, the thermostat must call for heat. Then the circuit board will flash rapidly. There should be power from the board up to the inducer motor. If there is too much resistance, the blower motor or pressure switch(s) will shut down the unit. I would suggest that if you can spin the inducer motor by hand, check for resistance. It may be frozen up or there may be water in the housing not allowing the blower to turn. Check for a plugged water drain at the bottom of the blower housing and make sure it drains. If the inducer blower does not even try to start, you will need to check for voltage from the circuit board. Not knowing for what you have for a model, I am unable to tell you if you should be checking for AC or DC voltage.

 

Get back to us as soon as you can with more info.

 

Thank you for your patience.
