exit water temperture changing

[cdhand]

I have a 3 ton waterfurnace 2 speed 3 years old entering water temp is 46 while the exit temp on high is going between 39.5 and 43.2 every 10 seconds. On low speed it does not change so that would rule out the water pump, as it's speed does not change. I just had a new air coil put in and was woundering if the freon charge being off might cause this. Does anyone know of anything that might cause this. Thank you for any help you might give.

Thank you Waterfurnace, for the effort to provide excellent customer service. I have not yet called my service company as I was not sure what was wrong. The model# is NDVO38A111CTL & serial#XK2389. One more bit of information when it is running on high the amp draw moves between 10.4 and10.8 AMPs My service co. is Crowther Heating & Air Conditioning # 435-1141. Again Thank You for your help.

Just to let you know what was found to be the problem, the repairman added freon and it got worse so he took some out and now it works fine. It is very important that the right amount be in there. Thanks for all help given. Curtis
