Someone, somewhere in Gilbert wants to go for a swim in their pool but they can’t because the water is very cold. They have a pool heater but it’s not doing much to make the situation better because it keeps making strange sounds. This could happen on any day throughout the year, sometimes you just want a warm and peaceful pool session but your pool heater is refusing to cooperate.

This can be very unsettling and annoying. It gets even more annoying when you have no idea what to do to help your situation. In this article, we will be discussing the most common reasons why your pool heater is making strange sounds.

There are several reasons why your pool heater could be making these sounds. Some of them are common and others are not so common. We will be looking into both kinds and also guide you through the process of rectifying each problem.

Reasons why your pool heater makes strange sounds

• Clogging
  This is one of the common reasons. You may have a clogged filter which will result in a poor flow of water for the pool heater. In many cases, this is a major reason for the noise because the pool heater would not ignite due to the low water pressure. To avoid this, ensure that you keep your filters clean by maintaining a periodic cleaning routine with pool equipment repairs Gilbert AZ.
• Faulty blower fan
  This is not a common reason because not all pool heaters have a blower but it is important to mention it for the sake of those that have one. If your pool heater has a blower, it might have a loose fan which could be the reason your heater is making weird sounds. If this is the situation, it is best to get a professional to look into it, to avoid worse damage.
• Faulty pressure switch
  The pressure switch is responsible for measuring the pressure between your pool pump and the heater system. When the pressure is inadequate, the switch turns off the system. A faulty pressure switch can keep your pool heater from working properly even at the right pressure. If you suspect this might be the cause, you can test it by measuring the voltage across the terminals.

  In situations where the switch is the problem, you can bypass it to make use of your pool temporarily. However, it’s not advisable to use this as a long-term solution. Replacing the faulty switch is the best option to avoid unnecessary hitches in the heater’s operation.

• Loose ducts
  Just like many water systems, the pool heater system has ducts for the inflow and outflow of water. These ducts are fitted at certain points and tend to become loose over time. When they become loose and water keeps flowing through them, they make strange sounds. To correct this, you would need to tighten the ducts and if that does not fix it, get a professional to help.
• Accumulated calcium
  This is quite similar to clogging but the main reason for this is different. When you have hard water in your pool, as a result of the pH levels being off, you begin to have deposits of calcium in your pool. This calcium-concentrated water gets pumped into your heater and some calcium accumulates in it; thereby, clogging the system. This could be the cause of the strange sounds from your pool heater. This can be prevented by monitoring the pH levels of your pool and it can be fixed by getting professionals to help get rid of the calcium deposit.
