I don't have a manual, and I'm not sure if you are describing the owners manual that comes with a new heater.
This looks like it probably is the manual for my heater, but there is nothing in these manuals, other than basic troubleshooting tips. You need to have repaired them to diagnose more difficult problems. There are no error codes for these older heaters. Have you ever tore into any Toyo heaters.
I have 9 of these Toyo heater's in my rentals, so I know the basic troubleshooting procedures, but I need someone who repairs these stoves for a living to point me in the right direction. Do you have anyone in Alaska where there are many of these heaters in use on your help roster.
Hello again Dan, we have a lot of talent here, including people who have worked on that type of stove. I don't think we have anyone from Alaska though as far as I can tell..It is most likely a problem that will resolve with replacement of the control module or one of its primary sensors judging by repeating time frames... and knowing that the Achilles heel in these appliances is the electronics pervasively.... I would say that I am in the 90% accurate range on that assessment, but not 100%.Let me know what you think, we can go from there if you wish,Phil
The problem ended up being basically a build up of soot and deposits in the fuel line and firepot. The circuit board and control module seem to be doing there job.
