DEPENDABLE 92 WON'T START . ALL SWITCHES CHECK OUT. CAN'T DIAGNOSE CIRCUIT BOARD


Hello my name is Heath it will be my pleasure to assist you. First thing to do is go to the furnace take off the lower blower door and locate the circuit board turn the power off to the furnace. In the circuit board there should ba a small car like fuse usually 3 or 5 amps check the fuse it is probably blown replace the fuse with the same amperage fuse and then turn the power back on on the furnace and check the operation of the furnace.

Purex Triton MiniMax Plus 400 power light is not turning on nor is unit. Checked for power going to unit and no fuses appear to be blown. Thoughts on what might be the issue? Thanks, Dan


if you have incoming power, you may have a bad transformer. those systems run on 24-28v. you can check from yellow wire to yellow wire coming off the transformer to see if you have anything coming out. must check wires coming out of the transformer to each other, it won't register if you check each one individually to ground. hope this helps...

Just installed ignitor PP200 & Gma 10-R fuse, unit ran for approx 4 min & blew the fuse & burnt the ignitor up . Our parts available thru your location. Is their a troubleshooting guide...


It sounds as if you have a defective control board.

Find your exact model (example= B100T). Then, go to this page and find which board is in your particular model. Don't guess. http://www.reddyparts.com/master_heater_reference.htm

Then, go to the shopping cart for pricing & shipping cost.
