    MasterTemp 250 not heating - Ignition Lockout

    I have the manual and when I go through the trouble shooting guide the only thing it says is to set up temperature higher than the water temperature. I didn't find anything else unless there is better trouble shooting guide somewhere.

    MasterTemp 250 not heating - Ignition Lockout

    If it is the gas valve than I should be able to get some voltage there or not? I am not sure if I should measure AC or DC there. Thank you for all your help!!!!

    Can not smell gas at all, 0. Service heater light off No LEDs on the back of the board on I am not sure how to find out if the heater goes through three tries. (pump and blower are too noisy) LED on the ignition panel blinks three times Outside valves are opened

    MasterTemp 250 not heating - Ignition Lockout

    Thanks. I will check the gas. 1/ Over all this conversation do you still have feeling it is most probably the Ignition Control Module? How about the main board? I remember the display on the main board showed strange characters 2 months ago but I switched off and on the breaker and everything...

    MasterTemp 250 not heating - Ignition Lockout

    I was trying to measure the gas valve but I am not sure which wires since there are 8 of them. The two of them going down to the solenoid have 0V. Now the question is if I am measuring correct wires and also if the 0V is because of faulty board or some faulty sensor.

    MasterTemp 250 not heating - Ignition Lockout

    Unfortunately I don't have analog meter and I am not sure about the RMS. I have GE2524 multi meter. The gas valve has been all the time on. How could I test if the gas really comes to the heater? All the pipes are tight. I would have to disassemble the pipes. I am trying to trouble shoot it...

    MasterTemp 250 not heating - Ignition Lockout

    1/ I have a digital meter and this is what the manual says That means that 50V on the digital meter does not mean the module is bad 2/ Well the new unit would cost $2,000 and that is way too much for me considering we are using it 5 times a year

    MasterTemp 250 not heating - Ignition Lockout

    I don't have any info from the history but it could be year 2007. I have replaced the exhaust sensor in 2015 and since that time worked without any problems. We are not using it very often but approximately 2 months ago still worked perfect. There were no changes lately. The heater is connected...

    MasterTemp 250 not heating - Ignition Lockout

    I went through the troubleshooting guide. I don't smell gas at all. I don't believe it is igniting. The new igniter has 90 ohms and there is around 50V when I switch the heater on. It seams to me the solenoid is not letting the gas in but I am not sure how to troubleshoot that. The heater light...

    MasterTemp 250 not heating - Ignition Lockout

    Hello, I am getting the ignition lockout signal on our pool heater. No other error code no led on the mother board. I have already replaced the igniter but that didn't help. Could you please suggest what else to check and how? I didn't find anywhere how to check if the gas is flowing in? Thanks...
