Question about Jandy Laars Lt 400,000 Btu Heater

1 Answer

Just replaced the temp control board, but no blower and after a minute both high limit and service lights flashing. Technician told me that in addition to the board it could also be the Fenwal ignition controller. These are expensive items, so if there are other suggestions I'm all ears.

Hi,
Yup, he is right....they should never build those parts into a piece of heating equipment that sits outdoors 24/7....stupid engineering....

The start button light is blue, on the screen is beeping the key. i can't use any of program. it shows one minute till the end of drying. what to do?


The exact definition of this error when the clean light is blinking means that your dishwasher is failing to heat the water in an allotted time. This problem can occur on Whirlpool, Kenmore, Kitchen Aid, Jenn-Air, and Maytag dishwashers. The error can be caused by numerous issues but the first thing you want to do is reset the control board.
-To reset the control board press: high temp wash, heated dry, High temp wash, heated dry, high temp wash, heated dry, high temp wash, heated dry, high temp wash. If you don't have a "heated dry" button, use the "air dry" or "energy saver dry" button instead.
-All the lights will go solid at which point you press cancel to reset the board.
-If the control board doesn't reset, it's likely that you've just got a faulty control board and the control board will need to be ordered and replaced.
The next step in this process is to start a new cycle and see what happens. If the error code returns, then you'll want to reset the board again and check several things. The most common reasons for this error is because the water coming from your household is just too cold. The dishwasher is expecting 110 degree water to enter your dishwasher, so if your pipes are cold, the water may only come in luke warm. To correct this issue, just run your faucet next to the dishwasher until the water coming out is hot. On another note, make sure the dishwasher is washing with good water pressure. You can put a cup in the upper rack facing upwards and run a cycle to see if it will fill within 10 minutes of starting the cycle. If it doesn't fill with water then you know that the dishwasher isn't producing enough pressure which, in turn, will cause the water to not heat. You'd want to take your pump and motor assembly apart to clean inside if you had a loss of pressure.
You could also have a failed component including a faulty heater, control board, or high limit thermostat. You'd need to uninstall your dishwasher, disconnect power and lay it on it's back to check the resistance of the heater as well as the resistance of the high limit thermostat to confirm if they were bad or good. You should get tangible reading of between 5 and 30 ohms on the heater if it's good and less than one ohm on the high limit thermostat. If both of those devices check good, then replace the control board because that's the one device you cannot test.

My bush tdv6w vented tumble dryer is not heating up


If your dryer is an electric dryer, it is sounding like you have either a bad heating element or one of the two limit switches are open. The limit switch is an "overtemp" device to shut down the element if it gets too hot from air restriction. Lint build up in the blower and ducting is a major cause of restricted airflow across the heating element. Excessive tripping of the limit will result in an "open" limit switch and continual failure to generate heat. There should be one limit switch built into the heating package and the high limit will be located on the drum usually near the top, though there are some near the bottom of the drum as well. Any attempt to find and replace must be done with the power off as you are dealing with 240 volts.

If your dryer is gas fired, you've had a misfire probably due to a defective hot surface igniter or bad control module. Unless you are fairly capable of learning as you go, and have the basic tools for troubleshooting you probably need to call a sevice technician.

Hello, if you are referring to,the blower motor then most likely the relay on tne integrated contol board is malfunctioning. Unfortunatly the whole board must be replaced in this case.

Have Goodman GDS81155CNA, throwing open high limit relay. Have to pull main breaker to get to reset. I have already taken the entire furnace apart and cleaned it (completely, motort, evap coil cleaned,...


What about the safety limits for over heating? You have tackled all obvious problems, I am only throwing this out there because while the high limit is jumped out, to get the open high limit is definitely strange. So i would be tracing my wiring backwards from the relay to see what else is in line with it. This is not a solution but only a suggestion before running out to purchase the main control board, as most places will not accept a board back if that is not the culprit. Good luck with this one it leaves me slightly puzzled??

I have a dyno glo rmc-fa100dlx forced air heater. It will light and work for a few minutes, up to about 5, then it will stop heating and the fan will keep blowing. any ideas? thanks!


If the unit comes on and runs but then shuts down, that sounds like an indication of a high limit trip.

Most, if not all, furnaces have high limit switches that keep a constant check on the temp inside the furnace or air handler. On most systems, once this high limit switch has been made (got to hot), the limit switch breaks control voltage to the heating device (strips, gas, fuel, etc.etc..). The blower motor continues to run until the high limit has dropped in temp and reset itself.

On some models, the high limit is a manual reset, meaning you need to reset the switch yourself or shut the unit off and then back on to reset it.


Check all filters and replace as necessary. Check the coils and fan blades for dirt build-up and cleanliness. Check motor belt (if applicable). If all these fail to solve the problem, then your issue either lies within the blower motor itself not moving enough air for proper heat transfer. Or the high limit switch itself is failing.

Goodman Model GMNT100-4 Auto Power Down and Up until Temp.


Keep in mind all furnaces and circuit boards are not the same. Look on the back of the door to the blower compartment. You should find the list of diagnostic codes. Look up four blinks it should narrow down the problem. Although from the discription you gave it sounds lie the high limit control. When a high limit appears to be acting up it DOES NOT mean that the high limit needs replaced. The high limit just may be doing its job. This means that the furnace is overheating. Check your filters. Are all of your registers open? Is your blower set on the right speed? Is your blower going bad? Is the blower motor capacitor bad? Is your evaporator coil restricted? Just changing a high limit switch does not always solve the original problem!
Good luck....

Arcoair central heat /air conditioning unit


The blower motor kicks on when there has been a 24 volt control failure.

This usually means that a limit switch has tripped.

Most likely that would be a high temp limit switch or a rollout switch.

First, make sure the filters are clean. and the evap coil is clean. If eaither are dirty/clogged, it will partially block airflow, causing the furnace to overheat, causing the high temp limit to trip.

A rollout switch typically trips for three reasons.
1 flame rollout into the burner compartment due to poor airflow.
2 overheating af teh metal plate the rollout is mounted to, due to dirty, old, rusted components.
3 a bad limit switch.

If your unit has an LED light, count the flashes and it will hepl popint out the problem.
(locate the wiring diagram/flash code list, and correspond the flash count, with the code.)

First, check filters.
