Without more info like what the temp reading is and what the actual temp is it is hard to say. The first thing that comes to mind is temp sensor has gone bad. This is located on the side of the water manifold and the wires run back to the control board. You can order one with a model number from your local pool store. These are very easy to replace I hope this does it.

Heater set on 100 display shows 126


Obviously one (or both) is/are wrong. The easiest way to figure out which is to use a thermometer to take the water temperature to determine to actual temperature. Then you can decide whether or not to spend money to repair indicators or thermostats.

Why does it work OK all evening then a quiet motor sound but no blow. Cause=?


Hi there Philip, it's Jack at Dyson.

When your Dyson Hot + Cool heater has heated the room to the target temperature you've chosen (shown on the LED display on the front of the machine), it will revert to monitoring mode. In monitoring mode, the motor will continue to run at a low speed, drawing a small volume of ambient air past the intelligent thermostat. When the thermostat detects that the ambient air temperature is falling below the selected target, the heater will activate again to maintain the temperature.


From your description it sounds as if your machine is working correctly - it would display an 'E' or an 'F' error code on the LED display if there was an actual fault. However if you're still concerned I would encourage you to contact the Dyson Customer Helpline directly for further advice. You can reach our experts by calling 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

My dyson fan was serviced last winter by you as it was recalled now it does not work , the lights come on and the motor runs 2 seconds and dies


Hi Kathy, it's Jack at Dyson.

I'm sorry to hear you're concerned about your Dyson fan heater. However, this could be normal behavior from your machine, as the heater would usually display an error code if was an actual fault.

If the target temperature you've selected (shown on the LED display on the front of the machine) is equal to less than the ambient room temperature, the machine may run momentarily until the intelligent thermostat shuts it off.

The solution is to raise the target temperature, using either the remote or the controls on the base of the machine, until the heater runs. It's important to keep in mind that what you're selecting is the temperature you want the heater to heat the room to - so the machine won't run if the room is already at or above the target temperature.

I hope this helps, but if you'd like to discuss this with one of our experts you're welcome to call us directly on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

My dyson hot fan will not give out air under 24 degrees?


Hi Charlie, it's Jack at Dyson.

When you adjust the target temperature of your Dyson Hot fan heater (shown on the LED display on the base), you're setting the target temperature you would like the room heated to. The actual temperature of airflow produced by the fan heater will not vary.

If the heater won't run below 24 degrees, this is likely to be because the temperature of the room you're in is equal to or warmer than 24 degrees. The heater will only turn itself on if the temperature drops below 24 degrees, and once the room temperature reaches this target once again, the fan will turn itself back to monitoring mode.

I've attached our Getting started video below which shows how to adjust the temperature, using the remote or the controls on the base.

I hope this makes sense. It sounds as if your machine is working correctly, but if you'd like any further advice from our experts you can reach us at 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

Dyson hot and cold fan only works in hot mode


Hi there, it's Jack at Dyson.

When you adjust the target temperature of your Dyson Hot fan heater (shown on the LED display on the base), you're setting the target temperature you would like the room heated to. The actual temperature of airflow produced by the fan heater will not vary.

If the heater won't run below 25 degrees, this is likely to be because the temperature of the room you're in is equal to or warmer than 25 degrees. The heater will only turn itself on if the temperature drops below 25 degrees, and once the room temperature reaches this target once again, the fan will turn itself back to monitoring mode.

The temperature display indicates "HI"


There are two possibilities for this error. Either the temperature sensor is defective or the units board is not reading it right. Here are a few suggestions to determine the cause.

1. If your system has two temperature sensors you could switch the connections and if the temperature is still off then it is the board. If the display is correct then the sensor is defective.
2. The manual may have a table of resistance versus temperature that you could use to test the sensor with an ohm meter.
3. If you call Pentair technical support at 800-693-0971 they should be able to help you determine what is wrong.

I hope this helps

H4 Displays


H4 indicates "low temperature", possibly caused by a failure of the heater lamp or fuser. Sometimes this error is shown without an actual damage when the power cord is pulled without shutting down the copier first.

To cancel the error code, press [CLEAR], [AUTO], [CLEAR], [AUTO] in rapid succession. The display should go blank. Next, select 14 (clear low temperature code), press [START]. Finally, switch off and on the machine.

If there was no actual damage (i.e. power cord pulled), the machine should be OK again. If the error persists, immediately or after short time of operation, you will need to contact Sharp technical service for repair.

I have a minimax ch 150 heater and the heater is running but the water coming out is not as hot as it used to be. Though the heater is extremely hot on the outside. Any tips?


Check your SENSOR. With the Minimax ch heater, you might be using an 'IntelliTouch' panel that controls your equipment. If you are, check the reading that the panel says the water temperature is and then check the temperature of the water 'coming out' (spa??) manually with a floating thermometer. When the heater cycles off, check the difference between the 2 numbers. Say the panel says 102 & the thermometer says 95?? - that is a faulty sensor, telling the heater that the water has reached 102, so it cycles off before ever getting hot. If you're not using the IntelliTouch, you will be checking the display panel on the actual heater itself & again the floating thermometer. Now... if the temperature is less than a 4 degree difference you can always calibrate/or have calibrated the heater.
