My hot tub is pulsating once it reaches the programmed temperature. So it doesnt shut off, just turns on and off repeatedly, sounds like a reving rythmic engine.

My hydroquip cs6230-u pack on my hot tub shuts off for days and comes back on. None of the circuit breakers pop. The cold weather is coming and I don't want any pipes to freeze. I would also like to u


I do not know this unit so this is only a guess on my part.

I am not sure what you are by it shuts off for days. If it is hot that may also cause it to shut down but for less then an hour. The manual can be found by googling:

hydroquip cs6230-u pack manual

Several of the manuals show up. Be sure CGFI is OK.

This is what I found in the manual. Measure your water temperature it may be OK.

FREEZE PROTECTION - There are two(2) levels of freeze
protection integrated into the system.
1 - SMART WINTER MODE, this mode will activate any time the
temperature falls below 59BF. This mode will be active for a period
of 24-hours. In this mode, if a pump has not been activated in the
last 2 hours, the system will automatically turn it on for 1-minute
to prevent freezing. The "Filter Cycle" indicator will illuminate
while this mode is active.
2 - If the spa water temperature drops below 49BF, the heater &
pump will be activated until the water temperature reaches 50BF.
While freeze protection is active no other functions will be
possible.

What would cause 1999 Chevy Blazer to shut down


you could have a problem with the ignition module that is temperature sensitive. I have run into this a couple of times. the module reaches a certain temperature for a while and it affects the electronics in the module and shuts down. the only fix is replace the module in the distributor.

What would cause 1999 Chevy Blazer to shut down once it reaches a certain temperature? It will turn over but won't fire off. Computer said it was Temperature Sensor Sending Unit. Replaced it and still same...


The engine has an automatic shut down if it reaches a certain temperature to protect the engine. Possibly it could need a new thermostat for less than $20. It is possible the thermostat is stuck in the closed position not allowing fluid to circulate throughout the engine. Try it and see. Cheaper than a mechanic to replace it for you.

WHEN REVE UP CAR GLOW PLUG LIGHT COME ON AND OFF HOW COME


The engine coolant temperature sensor is sticking, replace it, when it gets hot it will stick on hot also and your car will go into limp home mode. They're only about 25 euro and your can replace it you self but on the vitara they're difficult to reach as the engine which was meant to be engine mounted transiaxally mounted transversely. Basically it's turned 90 degrees, so it's hard to get at, it's against the bulkhead. A little patience and you'll get there

Will not restart


Sounds like vapor lock. This is when the fuel turns into a vapor before reaching the engine (it needs to be in a liquid form). This is usually due to high temperature from the engine and environment. I would have someone check it out.

Car hiccups and stalls


Although your temperature gauge may show that it works, some models have a second temperature sensor for the engine management system.
That second sensor provides info which sets curb idle and timing advance. The "Cold start" feature is a part of this. The hic-cup is something of a bucking symptom as the engine controls toggle between hot and cold run settings repeatedly as water temperature is not stable.
In the past, I found several 1984 engines having defective thermostats which are tied into "Step-up" solenoids for the curb idle. What happens is idle speed is suppose to drop when the engine is hot.
When someone adjusts the curb idle while the engine is on the "cold setting", the setting(rpm) will be too low once the engine has heated up and the part drops to a hot setting.
So to clearly define your problem, you have 2 stemming from the same defects. The "in motion" problem is caused by timing changes based on temperature and the "idle" problem is caused by improper adjustment of the curb idle solenoid because of unstable operating temperature.
What you want to do is change your thermostat. This will give you a stable temperature. Then let the engine heat up and you should notice a "click" and the engine should idle down. It may stall. Then turn the idle rpm up until the engine will not stall.
The hic-cups should disappear once the operating temp is reached. If you still have problems then look for the water temperature sensors before replacing expensive parts.

Won't start - lights come on bright & fine, but the only sound is a whining hum. It did this a week ago, after sitting all night in parking lot started right up. Now it is doing it again. Temps are...


hi..

this may be because due to high temperature the fuel inside may reached it flash point so gassification may occured.
so no atomisation of fuel may takes which doesnt fire. this may be the reason. please keep the hood open for some time the ouside air cools it prevents fuel reaching the flash point.try not to keep the car in hot places

if my answer was useful please rate me

Fan stays on after turning off car relay switch location 


when you shut the motor off and it is hot the fan will come on until a certain temperature is reached and then shuts off. this is to keep the engine from being damaged by excessive heat. it is controlled by a temperature sensor which is normally on the engine block near the thermostat housing.
