When picking replacement parts for your furnace, cost ought to not be as critical as a lot of companies make it. The cost of heating elements between a good manufacturer and a bad one is negotiable, as compared with the overall financial investment. The production time and quality of the parts acquired by picking a respectable manufacturer will more than make up the difference. Remembering the following pointers when picking a manufacturer will guarantee less downtime due to a defective product.
Manifold Heater and Cartridge Heater.
Cartridge heaters are used around the flow channel to guarantee uniform temperature levels Cooling And Heating Dallas Texas . It is essential to keep the distance between the heaters and the manifold equal or greater than 1x the diameter of the heating element.
Thermocouple placement ought to be located equally distanced between the heating element and the flow channel, and ought to be set deep to guarantee a precise reading.
If an internal thermocouple is used, it is essential to make sure that it is located towards the center of the heating element, depending on whether the controller is grounded or ungrounded.
Some of the most common reasons for failure include:
Lead short out.
This can be fixed by changing the lead type. If fiberglass leads were used, this might be the cause. Hot runners by nature create gases, which with time, saturate the fiberglass material, causing it to short out between the leads. Depending upon the ambient temperature around the lead area, Teflon leads can be used to correct this, as they are more resistant to gases.
Internal thermocouple not reading properly.
This can be caused by 2 different reasons. One reason is the thermocouple must be found in the center of the heating element. If not, you will never obtain a proper temperature of the flow channel. The other reason is whether or not the unit is grounded or ungrounded. Consult your controller manufacturer to determine this.
