L is no longer available, the only thing you can do is re-wire the control section to use a simple thermostat and timer to control the condenser and leave the old controls for a thermometer only.

Why won't blower shut down after gas cycles off?

The circuit board should control the blower and on that board there are very small relays that may be sticking closed. Board may need to be replaced. Also, most furnaces have high temp safeties. When the safety opens, the circuit board thinks there us a high temp problem, them brings blower on to cool it down. These safeties are normally wires in series with each other and possibly with other components. It also could be a shorted control wire or t-stat allowing "r" to "g" connection

After turning off the unit the display is off but the unit is still running.

If it has humidity control and the cool is still on but set temp is higher than the room temp, the humidity control will override set temp. If it has no %rh control then it probably has a circuit board fault; micro relay is stuck closed and board needs to be replaced. Its probably the circuit board. On it, there is a little black box(s). About 1" X 1/2" in size. With long run times the small contacts inside will fuse/melt together.

Spa Heater problems- Balboa VS-501 controls #54356.

Use a high quality external temp probe and make sure the temp sensor in your system is correctly reading the water temp.
If the water is truly 110 then you may need to replace the board completely.

Model JGBP28DED1WH Stove heats up then temp. drops off ,have to shut off and restart stove.I have replaced ingither in stove,control circuit board,whats left to replace.???

This problem is most commonly caused by a weak ingitor, but as you stated that you have already replaced that, the next most likely cause would be the oven temp sensor, part # WB21X5301 . The control circuit board is very rarely the cause of such a problem.

I have a whirlpool side by side refrigerator model no GS5SHAXNB00 refrigerator light blew this morning i replaced the bulb no lights working on refrigerator side and temp control settings

you need to replace the main/board for sure located in the lower rear left hand wall of the unit in a plastic case, it will have 3 wire harnesses unplug the unit,undo the plastic container and unplug the the board and there will be a burned spot on the case and burned trace on the circuit board, reason being,this is very common on any of these sideXsides,if a light blows out in the refrige compartment it puts a surge on the board and burns the circuit trace open,this makes the digital temp read-out go dark and if the lamps light at all they "strobe" dimly or not at all,and you will hear a clicking of the relays in the rear area trying to latch the light bulb circuitry, but cant because the main/mother-board is defective now

sounds like you need to replace the control board, i believe there may be two parts here - if there are, try replacing the power control board before trying the electronic control piece... this is the board that has the low and high voltage circuits and relays.
