I tried this in the 'Everything Else' section and it sunk without trace in 24 hrs. I'm going to try and troubleshoot this with gas off and would appreciate any 101 tips. My gut says that there aren't many techs out there that understand and can trouble shoot heater issues. I'm handy with a DVM and was a field service engineer on IBM mainframes for 20 years so any help would be appreciated. I'm not going to monkey around with the gas lines, that's a pro's job. I must say that if the Raypak is one of the better heaters, the others must be total *****
Thanks.

Folks,
I’ve got some problems with a Raypak 407A. I had it firing up but it failed to turn the blower motor and failed with FAN after about 5 secs or so. I’ve replaced the fan relay with the same OMRON LY2F, no effect, still FAN error. Then it regressed to SPK only on the display and no fire up at all. Also I can hardly hear the ‘chirping’ sound that accompanies the SPK message. If I put my ear to the gas valve I can just about hear the ‘chirping’, it was always way louder than that. I was able to see 24V at the violet/black wire lug on the relay when it was firing up and before I got the FAN message. I also have 120V on the red and black inputs to the relay. I never did see anything coming across on the black/white wire or red/white wire from the relay to the blower motor. Now of course it won’t even fire and sits in SPK mode with a hardly audible ‘chirping’. I think this will end up with a call to a tech but if there are any basic checks I can carry out, I’d appreciate it.
Thanks.
