The high temperature limit may be shutting off the heaters when they registera high temperature conditiojn that is dangerout. Have you gotten to run the heater long ehough to take a temeperature reading betweeen the supply and the return? also do you have strainer in line with the piping to the boiler.and is there a pressure switch for if the unit develops too much pressure. And how can you tell how many gpm your moving thru the boiler? these are the thing that a compenent service technician can check out and correct the prolem. exspecially since this is a boiler and if its improperly repaired it can explode and do lots of damage..that being said I strongly reccommend that you call a service company to service your boiler. THaanks for using Fixya

What to check when you air conditioner will not stop running:


If you discover that your outdoor air conditioner and/or heat pump runs continuously even with your thermostat off and the indoor blower is off, the most probable cause is a stuck contactor. In most residential air conditioners / heat pumps, the contactor is the switch that allows voltage to your compressor and condensor fan motor; therefore, allowing them to run. The contactor allows line voltage (normally 208 - 240 volts) to pass through a set a contacts to your motor. The contacts pull in when the thermostat calls for Cooling and they "open" when the thermostat "satisfies". This is accomplished with the use of a low voltage coil. When 24 volts is applied to the coil, it creates a magnetic force that pulls the contactor in to close the contacts. When the 24 volts is removed from the coil, the magnetic force no longer exists.....a spring will force the contacts back "open" and stop the compressor and fan motor from running.
The contactor is considered a wear-n-tear item as, eventually, the contacts will wear and begin to "pit". Eventually, they will either pit so severely, they will not allow enough voltage through them to operate the motors OR they may allow enough voltage and then overheat and weld themselves together. Often times you can lightly tap on the contactor and it will "free" the contacts and stop the motors. Unfortunately, once the contactor starts "sticking" it is highly likely it will stick again. Therefore, it is recommended that the contactor be replaced at first sign of sticking or when the contacts show signs of damage/overheating via a visual inspection.

Here's a video that might be helpful to you. :-)

I changed the contactor and the thermostat, the contactor does not kick in right away, is it supposed to? is there something else i need to change? thanks


The Cspaxi series also have a pressure sensor which senses the pressure inside the heating tank. This sensor connects to the coil on the contactor, insufficiant pressure in the tank will cause a delay in the contactor activating. It sounds like your problem can be caused by insufficiant water flow from the pump, a clogged or pinched water line to the heater, or a faulty pressure sensor.

1 Answer

I have an older Catalina spa with acura controls. The tub will no longer heat up. The pump cycles but the heater and light does not come on


These older style controls are easily repaired but require some electrical diagnosis expertise to determine the problem.
1. Check the pressure switch to make sure it is working properly - Use a continuity checker to see if the pressure switch is closed when pump is running. If not then check for proper water flow. Dirty filter, obstruction in plumbing. If flow is good, replace the pressure switch and see if heater works.
2. Check to see if the heater has 220V at the heater terminals when heater circuit is running. If not, then check to see if the heater contactor (relay) is actuating. Check Hi-limit switch, Thermostat and pressure switch for continuity. If heater has voltage, check for current draw, using a clamp style amp meter around on of the heater wires. look for about 20 amps. If voltage is present but no current draw, the heater is bad.
3. The spa light is a completely separate circuit, check the air switch, air line, button and light bulb. Its a 12V AC circuit.

Carrier 38CKC042300. oUTSIDE UNIT FAN WAS TURNING REAL SLOW. ac UNIT IS OFF BUT FAN TO OUTSIDE UNIT IS STILL TURNING. sHOULD NOT BE TURNING AT ALL WITH AC UNIT OFF


The outside fan may run if the unit is in defrost mode this is normal for most heat pumps it is there way of trying to keep the outside unit from staying iced over so the next time the unit runs it will have air flow through the coil and the ice will not be there to prevent air flow.

Dryer start up fine then the gas turns off as ignitor continues


Hi Jim. Perhaps this will help you.

The burner assembly consists of the gas valve, the igniter and sensor, and the thermostats. The gas supplied to the appliance is turned on and off by the gas valve, as follows:


  • First--when you close the dryer door, set the timer, and press or turn the Start button--the motor starts. When it reaches full speed (in about a second) a switch on the motor turns on, which allows the electricity to flow through a simple thermostat to one side of the gas valve.

  • The gas valve then sends power to the igniter, which glows bright orange.

  • As heat and light from the igniter warm up a sensor that's right next to the igniter, the sensor circuit opens, then supplies power to the other side of the gas valve. This completes the circuit and opens the valve.

  • Once the valve opens, the gas rushes out and the igniter ignites it. As the gas burns, it keeps the sensor warm, which keeps the gas flowing.

  • When the dryer reaches the pre-set drying temperature, a simple thermostat turns off the flow of electricity to the gas valve and therefore turns off the gas.

  • When the temperature in the dryer falls about 20 to 30 degrees, the thermostat again allows the electricity to flow through to the gas valve, and the cycle starts over.

If you selected the Automatic setting, the cycle continues until the clothes are dry, then the timer advances and turns the dryer off.

If you selected a timed setting, the cycle continues until the time has expired, then the timer turns off the dryer

Comressor won't kick in...


Check contactor on outside unit for burned contacts. Try to manually press the contactor with INSULATED screwdriver to test. Should be some **** on cotact buttons. Hope this helps. Let me know. Good luck

A/C unit will not shut off


pls the connection of the thermostat is
C- COMMON
R- LINE
G - FAN
Y - COOL (compressr contactor)
W- HEAT ( heater contactor)
after you check the voltage 24 v between r and c slect cool then set thermostat at low temp the fan will start after the compressor will start

No Heat from Spa


Tcarrigan,

Heater contactors "buzzing": Do you mean normal buzzing or extra loud buzzing? Loud buzzing or chattering can be caused by low voltage to a contactor. If normal sounds, then probably the relays on the contactors is working, but the contacts may be stuck, or burned enough so as not to make contact. First, get a voltmeter and check for 240 volts AC at the heater contactor terminals. If the voltage is low, most likely you need to check the contactors further. Check for dirty contacts, clean if needed. If the contacts are not moving when energized, then you will probably need to replace one or both of the contactors.
