Troubleshoot a Modine Hot Dawg Heater
Troubleshooting Modine Hot Dawg heaters is pretty straight forward. Most problems are solved with a few simple questions.
This time of year many, many people are in the market for a heater. We sell tons of them. Specifically, we sell many Modine Hot Dawg style heaters and also sell a large selection of other Modine heaters. For the most part, we never have a problem with them since they are excellent heaters, and everybody is happy.
There are times though, when a problem arises. We (being super awesome and all) attempt to troubleshoot the problem with our customers. We even have a guy, Charley, dedicated to it. So, it usually turns out well for everyone. Sometimes we get folks calling to ask about a heater we did not sell them or that is old or out of warranty. We help with these too, although we are less able to help in these cases than with a Modine Hot Dawg heater that we sold and is under warranty.
To help out in the event you ever run into a problem with your Modine Hot Dawg, we’ve put together this list to help you troubleshoot on your own. This list covers the large majority of issues that you might encounter with your Modine Hot Dawg Heater, both natural gas and propane. First, some housekeeping:
- Warranty – The warranty on a Modine Hot Dawg is always only going to cover parts; not labor. This is pretty typical for a warranty of any kind. In most cases you will also need to purchase the warranty parts, and upon verification that the defective parts are a warranty issue, the manufacturer will issue a credit.
- Installation – The first thing we (or anyone for that matter) are going to ask is whether or not you had a certified professional install the heater. If you did, then many times it’s best to just contact that person or company because they will be better equipped to troubleshoot the heater (and you won’t have to deal with any of the hassle). That way, in the event the problem has something to do with the heater being installed incorrectly (as opposed to mechanical malfunction) it usually won’t cost anything to fix.
The Rundown on Your Modine Hot Dawg Heater
If you installed your own Modine heater then it is your responsibility to handle all the details in getting your Modine Hot Dawg heater up and running, which may or may not be an inconvenience to you depending on the situation.
- What is the problem – For the most part, the problem is the same every time; the heater won’t fire. As you might guess, there can be many different things causing that problem. Here is a list of questions we ask to get to the bottom of it:
- Does the heater turn on? – Once the Modine Hot Dawg heater is hooked up and wired, the best way to tell if it is on is to check the power vent fan. If it’s on then the unit has power and is operating electrically.
- Are the electrical and thermostat wired correctly? – If the unit is wired up and should be on but is not, then there may be a problem with the wiring or thermostat. Make sure the wires are connected correctly. Also, it’s silly but it happens a lot, make sure the thermostat is set correctly.
- What is the gas line pressure? – If the unit wired, the fan is spinning, and the igniter clicking but there is no ignition, then gas pressure is the first place to check. A Modine Hot Dawg heater will not function unless the line pressure for the specific fuel is within a certain range. Keep in mind that you are almost always going to need a professional with the proper tools to do this for you. The line pressure settings are as follows:
- Natural Gas: 6-8 WC
- Propane: 12-14 WC
These steps should have brought you to some kind of conclusion as to the problem with your Modine Hot Dawg heater. If none of this worked for you, try looking in Modine’s own Troubleshooting Guide.
