Question about Pentair Minimax NT Heater

Nt mimimax heater showing error message and wont heat water.

I unscrewed panel box on the side and noticed that the blower was barely turning and the unit was hot. A pool technician informed me I need a new blower, about $700.00, but that he would replace the entire unit as this pentair heater is not a quality product. His estimate was about $2400.00 for a new heater. I have never had the heater working since I purchased the house over 1 yr. ago. Not sure which direction to take. Any advice apprec. Thanks.

I would not put any BIG money into that heater.Nothing but problems! I would recomend a Raypak/Rheem heater or a starite.

Bradford-white water heater wont heat water.the blower motor hums but wont blow.also,pilot light wont light,is this just a safety feature?

Water heater is not identified and gas valve is not known.
Review options below:

1) Add a comment and describe what gas control valve is on the water heater, and model number from label on side of unit. Include what you have tried so far.

2) Try unplugging water heater and see if water heater resets.
Disconnect blower from gas valve, then plug blower in to see it it operates.
This will eliminate or include blower as suspect.

3) Open following link to download service and product manuals to help troubleshoot exact model.

4) Open following link to identify gas valve.

I noticed when it rains passenger side floor gets wet check for leaks from windshield no leaks. then i noticed a strange sound when i turn the heat on. now heat doesn't work at all

I have seen some problems with water coming in through the cabin air filter. (Also known as passenger compartment air filter - see picture) Sometimes this is caused by a buildup of leaves and debris in the cowl area that causes water to overflow into the filter area. Sometimes this is caused by the filter not being installed correctly. I have even seen the water diverter that goes over the top of the filter get discarded by quick-lube "specialists". Anyway, these conditions will allow water to enter into the vehicle through the heater system. Many times I have seen the filter so badly damaged by water and debris that it ends up in the blower motor and stops it from running. This is where I would look for the problem first.

I am getting an E04 error message and the fan work turn on. The lights on the front display are lighting up except for the heating. the service light is on too.

An E04 can be alot of things.
If the fan is working, then the first thing to check would be the air/fan switch, or the air switch tubing itself. They installed the air switch tubing right over the burner tray so it melts and cracks quite often. This is one of the readons this model was discontinued.

The air switch is inside the cabinet on the right side behind the little metal box. remove the screws to access. The air switch is about 3" and round with a vinyl 3/8" tube coming out of it.
Also remove the top side panel on the right side. Now follow the air tubing from the switch to the blower in the side panel. Remove this tubing and inspect. Chances are there are som small cracks and things you will find. If this is the case, replace the tubing and try to restart heater.

If you did not find the tubing to be bad, then its your air switch. I would like to list the part number, but the model and BTU's were not provided above. Here is a link to the manufacturers parts and manuals list.

Hope this helps

My heat in my 1992 gmc jimmy barely comes out and barely any heat. My car barely heats up in the winter as it is. And i have checked the water levels and everything. So i was wondering could the problem...

Check the actuator motor on the heater and make sure the heater doors are fully opening and closing to direct the heat or ac. It is inside on the heater box in the end close to the driver side.

I just replaced the control module and flame sensor. The heater fires up for about a minute then the blower comes on and it appears to blow out the flame. It will fire up again and work until the blower...

This is backwards. The blower comes on first then after the air pressure is good in the exaust it will turn on the power to the ignitor and open the gas valve. If it is doing what your describing there is something wrong with the way it is wired. But many times people will mistake the noise of the blower comming on for the flame and the sound of the gas valve and the ignitor for the blower kicking in. This is probally the case. If you have water in the fire box this is a much bigger problem with your heat exchanger and it will do damage to other components. If this is the case it is time to replace the heater. All of this is symptommatic of bad water chemestry and you will need to address this or you will damage the new heater and chemecal damage is never covered by warrenty. Good luck.

Water dripping inside car

It sounds like you have a drain stopped up on the air conditioner system. You have to get under the vehicle prefferably with it on a lift and clean out drain.
